Playing in ROG with shipwrecked compatible world(seaworthy not yet built, no second world gen yet) was spending summer in caves for 15 days (whole season) and when i exited the caves game crashed and days in caves are not count! then i played summer again for 15 more days in caves and exited same crash still summer! You can see in the picture attached total days and world days with 30 days missing. Note: spending a short amount of time in caves doesn't cause crash when i go there occasionally (less than a day).
Steps to Reproduce
Spend some time in caves and exit= game crash then days reset to before cave entrance
