What version of forge are you using?, and what other mods are you using?

Wykks · Answer 2 · 2015-03-23T21:06:56.000Z

I am running Cauldron 1.7.10-1.1307.06.218 (unoffical fork) and I know it's not supported anymore blablabla. I just use this because of the performance improvement (don't care about bukkit plugin).

Soooo I did test it on a forge server (1307) and it doesn't throw java.util.ConcurrentModificationException.

My bad, I guess I'll have to play without planter... Not the end of the world.

Possibly disable any option that has to do with threading? I think Cauldron threads chunkloads and Orebfuscator...
