During Auto-save, the game freezes for 2 to 10 sec, it does not load chunks, it does not load certain faces of the blocks, it does not load the destroyed and placed blocks, the leashes remain blocked (sometimes they break ).

The more we explore the world, the more these bugs grow.
Changing the number of chunks and the number of fps does not change anything.

To reproduce the bugs, the game must be played with 2, 3 or 4 players. You have to explore a large part of the world (4000x4000 area) and wait for the Auto-save.

Conclusion: The game becomes almost unplayable when auto-saving with 2 or more players.

 
Thank you for solving these problems.
