Error Game is already saving - Again/Still
Original Post / Claim of fix: https://support.keenswh.com/spaceengineers/general/topic/error-game-is-alredy-saving
This is still occurring. I've been having to use Save As as a work around, and Backup saves are non existent on these saves. More than 2 hours passed between Me manually saving (because I was afraid a boom was about to happen). I hit the Save button in the menu, got 'Game is already Saving'. Hit Save As.
Decided to exit out and see if it would resolve the problem, checked to see if there were any backups in the Save that was running before I did a Save As, and there were no backups in it, despite having backups set to 10. Saving (via Save As), exiting the game completely, and then re-entering seems to at least fix it temporarily.
