I tried it on 3 saved games.
Windows 10 Pro x64 PC.
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) Client VM (build 25.171-b11, mixed mode)
- Smallest save files (a new game mission mode, literally was a new game). Updated successfully.
- Second smallest saved game (mission mode day 2). Update successfully.
- Largest file (endless mode day 49). Not successfully. Long description below.
I actually tried it on the largest file first, no success. Then on the two smallest saves, success. Then on the largest again, no success.
It doesn't crash, it's just stuck. The message say "fixing world chunks" and stays like that. I left it like 20 mins on my first try. Restored backup and try again. the same thing. It looks like it's stuck on the same chunk (based on the files date).
I just Alt-F4 the game. Don't see a new crash log.
Maybe tomorrow I could try it on another pc (ubuntu 18.04 old-ish laptop). I have other saves there to test out too.
I backed up before testing and after each failure. How could I help? Send you just the pre-test save? Send you the pre-test and the two post-failure saves? As I said, no crash log available.
