Crimson Moon Known Issues: Crashes, Co-op & Saves
Check officially reported Crimson Moon crashes, co-op disconnects and save problems, with dated evidence, issue filters and confirmed-fix boundaries. Research checked: September 7, 2026Start with your symptom: game crashes, co-op freezes or disconnects, or save loss and Steam Deck sync. For setup rather than a connection failure, follow the matchmaking and invitation steps.
Current scope: the launch issue list was rechecked September 7, 2026; the official page itself still carries a September 1 date. “Confirmed” means the studio listed the issue, not that every platform is affected or a fix has shipped. Platform and severity labels below are our tracking categories unless the source names a platform.
Has a patch fixed these problems?
The September 3 PC announcement confirms Patch 1.0.0.1 for keyboard/mouse remapping and sensitivity. It does not establish fixes for the crash, co-op or save issues below. The launch support page mentions a planned Hotfix 1.0.1; a plan is not a release confirmation. These version names must not be treated as interchangeable.
We rechecked the official Steam announcements on September 7. Use the Patch Tracker for dated records. A fixed-version cell marked “Not verified” means we have not confirmed resolution, not that every player will still encounter the issue.

What should you include in a support report?
Record the platform, installed version, exact error and steps before the failure. For co-op, add whether you hosted or joined and whether you used Quick Match, an invitation or a code. For save problems, avoid deleting or overwriting files while trying unverified fixes. This is precautionary reporting advice, not a tested recovery procedure.
