Could you give me the names of which spidertron mods (if any) you're using? I downloaded a bunch and couldn't recreate that error.

I'll tighten up the checks regardless but I'd like to get more fixes done in one go if possible. Thanks for the help!

i dont use any that im aware of, i do have may mods but i never used a spidertron.
