Alright, that line in the code is for bobs refinery... attempting to fix the pipe connections, which does not exist... that could mean the entity itself doesn't exist? I would wonder if you have any non-default options set in bobs or if you have another mod that might be replacing refinery? Or is it the same modlist from the previous error?

its the same except i added in this mod > https://github.com/OmnissiahZelos/omnimatter/tree/master/omnimatter_fluid
which loads fine when i don't load that mod

Ohhh, dear... I haven't been able to support the omni suite of mods in any capacity for a while now. I'll take a look at it later, but the omni mods have been really unstable with my mods since at least 0.17, maybe earlier.

Well it loads with all of them fine minus omni fluid

Random bump to this, but I just tried loading up all of the Omni mods (including Omni Fluid) alongside Clowns/Bobs/Angels, and everything seems to be working properly? Not sure if anything more needs to be done.
