It seems some players have their game not correctly saved.
This issue appears to be related to asynchronous saving. While I investigate, I am temporarily disabling asynchronous saving and setting synchronous save as default.
If this causes lag during saving, you can use the ASYNC_SAVE command line to enable asynchronous saving again.
Changes:
Disabled async save by default.
Removed the SYNC_SAVE command line option.
Added the ASYNC_SAVE command line option.
Thank you for playing Chronoquartz!
