I updated the mod, recreated the config since it changed formatting, and it starts fine but as soon as I load into the world I get kicked shortly after - server closed. Something about item stacks and the Arachne mob, I guess?

This is the contents of my grimoireofgaia.cfg if it matters. It's consistent across server and client, and this was after attempting toggling enableSpawn to false to see if it made a difference(it didn't).

This is due to the mod accidentally calling a client-side only method.

I suggest disabling the Arachne through the config by setting the spawn rate to 0 for now.

The line of code causing the issue is not suppose to be there. I completely forgot to remove it before release.

So it's just the Arachne doing that, then? Alright, I'll see how preventing its spawns goes.

This should now be fixed in the 1.6.0-beta4.
