Two of my chests were suddenly partially emptied today at the same time as a long/far rollback was done.
One of my chests is missing an iron door, two and a half stacks of glowstone dust and a bunch of stuff i can't remember. The other one was filled with sugar cane and now only contains one small stack

Mods said rollbacks don't affect chests but it's nevertheless the case that items are gone.
This sucks.
