I found that Apotheosis was causing a crash with Goblin Traders installed.

Provide a crash report

I just tested with only the two mods and it worked, must be a combination with another mod.

I removed Apotheosis after this and it worked.

Apotheosis is not compatible with this

Alright, thank you for pointing that out. Not Enough Crashes was pinning it on Goblin Traders solely, and not on any other mods, but it may just be an error on NECs part, which I've seen plenty.

I also had trouble getting the world to actually load spawn, and Apotheosis was the only mod I removed, so it must have been the cause of both.
