https://pastebin.com/Eh4xi4hi i made a instance just with quark and autoreg, loaded a world, generated some terrain,saved it and reloaded it; it froze in 0% giving in the console this log!! i tried it with forge alone and 100% of the times,it worked just fine!!forge 14.21.1.2406 , quark r1.2-100 and autoreg 1.3-13 using multimc 5

Can't reproduce, using the same versions.

that's weird!! becuse when i remove quark the worlds that were refusing to load start to load normally! maybe it can be related to java itself
