Crimson Moon Patch Notes: Hotfix 1.0.1 Fixes & What's Next

Post-Launch Update Overview: Patch 1.0.0.1 & Hotfix 1.0.1

Since Crimson Moon launched on September 1, 2026 across PC, PlayStation 5, and Xbox Series X|S, developer Team Metal (ProbablyMonsters) has released two consecutive post-launch updates addressing player feedback from Steam (AppID 4317690), Discord, and Reddit:

Patch 1.0.0.1 (Build 162350): Fast-tracked the Alpha implementation of PC keybinding support and mouse sensitivity controls into players’ hands.
Hotfix 1.0.1: The first major cross-platform stability update targeting save and progression loss (via rolling backup saves), Steam Deck to PC save syncing, camera and lock-on behavior against large bosses, client crashes (including the Flesh-Wrought Egregore encounter), co-op issues, and UI issues.

Quick Symptom-to-Fix Reference Table

If you are checking the patch notes because you hit a specific bug in Gildenarch or Sanctus Clypeus, here is how the official updates address each issue—alongside clarifying two intended game mechanics that players frequently mistake for bugs:

Player Issue / Search Query	Official Patch Status or Intended System Rule	Update / Source
“Save lost / progression reset”	Added rolling backup saves for extra protection if a save fails to load, and fixed several unintentional progression resets.	Hotfix 1.0.1
“Steam Deck save not syncing to PC”	Fixed the issue preventing cloud saves from syncing properly between Steam Deck and desktop PC.	Hotfix 1.0.1
“Camera / lock-on glitch on bosses”	Improved lock-on camera behavior for large stationary bosses, plus tracking improvements around large and elite enemies.	Hotfix 1.0.1
“Crash during Egregore boss fight”	Fixed several crashes across PC and console, specifically resolving the crash during The Flesh-Wrought Egregore fight.	Hotfix 1.0.1
“Cannot rebind PC keys / mouse speed”	Added Alpha keybinding remapping, default reset, and mouse sensitivity under Settings > Keyboard > Custom Profile.	Patch 1.0.0.1 (Build 162350)
“Loadout Station locked / floating above me”	Intended Mechanic: A full run is 3 missions + 1 World Boss; returning to Sanctus Clypeus mid-run does not end the run, keeping the Loadout Station locked until run completion or death.	Team Metal Systems FAQ
“Purified Rare item became Common”	Intended Mechanic: Purifying any item permanently unlocks it at Common quality regardless of drop rarity; upgrade it with Gajov to raise its minimum quality everywhere.	Team Metal Systems FAQ
