Thought I'd give this one a try and got this:

what mods are you loading it with

A lot, I was writing up a list but the core mods were AAI Industries, Space Exploration, Tiberian Dawn and Rampant Arsenal. If I end up doing another round of testing I'll go through them all otherwise I'll send the list once I finish it (got about 100 so far)

Right, I've finished the list (edited from mod-list.json):

wow... can we narrow it down at all? i don't know if i have enough time to spend several days loading each mod

I'll let you know next time I strip it back. Might do it tomorrow morning depending on whether I get called into work or not

it's the space exploration mod and aai industries, i just tried it out. Don't have as many mods installed as hairydave, but try deactivating space exploration and the aai mods. The issue is not just with space exploration and it's dependencies, it seems the other (i have signals, sig transmission and programmable vehicles installed) cause the problem too...
Would love to have a patch for them, love both the mods :)

well now that we've narrowed it down to a couple it'll be possible to get another version out with a fix. if i can.

awesome!

love your mod btw, thx a lot!

hope you can fix it!
I love thaumaturgic alot!
