Chat history is no longer deleted after 30 days. Messages are now kept long-term in monthly-sharded storage, capped at the most recent 20,000 messages per character. The new layout also makes Steam Cloud sync upload only the current month's file, so syncs are faster and playing on multiple PCs conflicts less.
Fixes
Characters with memories but no chat history now appear in the Memory Manager list. Previously their memories existed but had no way to be viewed.
Interrupted Workshop uploads no longer leave staging folders behind. Leftover folders older than 24 hours are removed at startup — previously each could keep a full content-package copy on disk indefinitely.
Crash dump files are now capped. The app keeps the 5 most recent crash dump files.
