Quasimorph Post-1.0 Hotfixes Guide
August 2026 stability builds 1.0.561/562 and the follow-up Patch 1.0.1 QoL pass
Quasimorph 1.0 left Early Access on Steam July 31, 2026. Within the first week Magnum Scriptum pushed live hotfix builds 1.0.561 and 1.0.562, then shipped Patch 1.0.1 around August 7–8 with the promised interface and difficulty clarity work. This page is an unofficial digest of those Steam announcements so you know which bugs are already fixed, which RealWare story softlocks are gone, and how the QoL patch relates to the smaller hotfix builds.
Steam news remains authoritative. Cross-check the live client build string against Patch 1.0 Release Notes, the full Patch 1.0.1 Notes, and the longer Post-Launch Roadmap. New players should still begin at Getting Started — hotfixes and 1.0.1 polish do not change the Magnum extract loop.
Why hotfixes matter in week one
Launch week always mixes story bugs, graphics defaults, and mission UI glitches. Quasimorph’s extraction rules punish softlocks harder than most RPGs: a stuck RealWare floor can burn a clone, a kit, and a story checkpoint. Reading this page before you re-queue Reap the Whirlwind or chase achievements saves remakes.
Hotfixes and Patch 1.0.1 do not restore incompatible Early Access saves. Default EA slots still fail on the 1.0 branch; Unstable Beta slots may load. Backup %USERPROFILE%\AppData\LocalLow\Magnum Scriptum\Quasimorph\ before testing betas.
Hotfix 1.0.561s — August 1, 2026
Steam titled this build Hotfix 1.0.561s.a7d4f0d. Headline changes from Magnum Scriptum:
- Performance — the FPS limit defaults to 120 on first launch. If the client feels uncapped or stuttery, open Options → Graphics and confirm V-Sync or the FPS Limit slider.
- Balance — Stonecrusher is now treated as Power Armor, and related crafting recipes were adjusted. Rebuild or re-check armor plans in Armor and Resistances and Crafting and Consumables if you farmed Stonecrusher under older assumptions.
- Fix — weapon components that received traits in the previous update were corrected so trait/component pairing behaves as intended.
Practical takeaway: first-boot graphics defaults changed, and one armor identity shift can invalidate a midgame craft plan. Re-examine Power Armor recipes before you spend rare components.
Hotfix 1.0.562s — early August 2026
Steam titled this build Hotfix 1.0.562s.db7e1d8. It is the larger stability pass of the first week:
- Robbery missions — target items could spawn with a non-full usage count; that spawn bug is fixed.
- V-Sync — failed to limit FPS in windowed modes; windowed players should re-enable V-Sync if they still see uncapped frames.
- Gibil’s Blackfire pact — the effect no longer fails to end when a clone moves to another floor.
- Descend evacuation — the screen no longer briefly returns after the fade when you evacuate a Descend mission.
- Mission success UI — some missions skipped the success screen before orbital results; that flow is restored.
- Portraits — Jupiter and Europa portrait errors corrected.
- RealWare — Reap the Whirlwind — dying on the 4th floor no longer softlocks the story.
- RealWare — Reap the Whirlwind — throwing a TNB at Urparp no longer fails incorrectly.
If you abandoned a RealWare campaign because of a fourth-floor death softlock, update to 1.0.562 or newer and retry with a fresh story checkpoint rather than assuming the arc is broken. Route notes live in RealWare Walkthrough and Campaign Overview.
Patch 1.0.1 — QoL and difficulty clarity shipped
Magnum Scriptum previewed QoL and Difficulty Balance Improvements between the 1.0.562 hotfix and the next numbered patch. Patch 1.0.1 shipped around August 7–8, 2026 with the full pass — read the dedicated Patch 1.0.1 Notes for the complete digest. Headline themes now live in-game:
- Trading screen — clearer display of which items the selected station will buy, so you stop hunting demand lists in secondary menus. Pair the UI with Bartering on the Magnum and Trade Shuttle Guide.
- Difficulty selection — better presentation so new players can pick a more forgiving preset; Medium remains systems-heavy. Read Difficulty Settings after updating.
- Mission difficulty tooltip — clearer contract danger estimates and skull ratings relative to Solar System progression. Use Choosing Contracts alongside the refreshed tooltips.
- Mission preparation — more visible side switching (beneficiary versus victim), a prominent Start button, and richer prep information before launch.
- Inventory overhaul, HUD active implants, enemy AI tweaks, camera/minimap QoL, perk tooltip clarity, equipment presets, and Korean localization fixes — all detailed on the 1.0.1 page.
Hotfixes 1.0.561 and 1.0.562 remain the reference for stability and RealWare softlock fixes; 1.0.1 is the feature QoL layer that followed them. Patch 1.0.2 (August 14) is the next numbered step — sorting, AI Investigating, camera drag — see Patch 1.0.2 Notes.
What did not change
Hotfixes and 1.0.1 did not rewrite the 1.0 content spine:
- Five storylines and nine endings remain the campaign shape — Walkthrough Hub.
- Trade Shuttle still has three modes; Pact Department still exchanges low-tier pacts — Magnum Ship Guide.
- Clone death still deletes unextracted inventory — Getting Started.
- Console commands still invalidate achievement eligibility — Achievements Guide.
- Default Early Access saves remain incompatible with the 1.0 main branch.
Do not postpone learning Combat Stances or Room Clearing waiting for patches. Softlocks hurt; stance mistakes kill more clones.
Update checklist for returning players
- Confirm the Steam build shows 1.0.562 or newer before RealWare story attempts — 1.0.1 is recommended for the full QoL pass.
- Reset FPS Limit / V-Sync if you launched during 1.0 day-one defaults.
- Re-validate Stonecrusher / Power Armor recipes before crafting.
- Re-enter Reap the Whirlwind only after the softlock fix; keep extract meds stocked via Wounds and Medicine.
- Read Patch 1.0.1 Notes for inventory, trading UI, and mission prep changes after you update.

Quasimorph’s first August hotfixes removed story softlocks and graphics defaults that punished windowed and RealWare players; Patch 1.0.1 followed with the trading, difficulty, and mission prep clarity Magnum Scriptum promised. Stay current on Steam, keep backups, and treat every remaining bug report as version-specific until Magnum Scriptum closes it.
