Crimson Moon Patch Notes: Hotfix 1.0.1 Fixes & What's Next
Complete Crimson Moon patch notes for Hotfix 1.0.1 and Patch 1.0.0.1 (build 162350). Rolling backup saves, Steam Deck sync, Egregore crash fix, and 1.0.2/1.1 roadmap.
Crimson Moon Hotfix 1.0.1 adds rolling backup saves, fixes progression resets and Steam Deck PC save syncing, resolves Egregore boss crashes, improves large-boss camera lock-on, and follows Patch 1.0.0.1 Alpha PC keybindings.
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 |
