mc 1.16.5 - ATM 6 with magnesium

Reproduction Steps

place a mekanismgenerators:wind_generator from mekanism and your game will crash when you have magnesium also installed (doesn't happen without magnesium) after re-logging some blocks are not rendered properly and when you unload the chunk (client-side) and load it again after a while it will crash again.

I've been having the same issue: https://crashy.net/0UfqHYZuRJSMYhw935Mm
Hopefully this helps.

Edit: It seems to be almost certainly caused when the bounding blocks cross into another subchunk or whatever those are called. Also, sometimes it will work when you relog but other times it will not render other blocks and then crash shortly thereafter. I believe it's Quarks feature that allows you to place blocks around corners, if you do that and the resulting multiblock is in 2 subchunks then it seems almost a 100% chance that it will crash.
