I'm having desync problems with Ultimine and your mod. I A/B tested the different mods in the modpack and ended up tracing it back to yours. Disabling your mod ends the problem, but obviously I want your awesome mod in the modpack ;)

Started while farming Mystical Aggriculture seeds, ultimine started to cause desync problems. Some rendered mature crops were not getting mined, and sometimes, while gathering a non mature one, a lot that didn't look like grown up got harvested. Seems like there is a graphical desync between crop state and rendered state (note: It was common soil with red fertilazer from F4B and Pneuma crop stands).

Then I noticed the desync was happening with chopping down with ultimine regular birch trees, so I decided to investigate. Stack traces are not very informative, just this in loop:

But I AB tested the problem back to your mod. Hope it helps.

Thanks for your work and dedication.

I need the full log during the time you got errors

try 6.8, that should work
