It's something to do with fly mod calling something in statement library that conflicts with some code in tech reborn.

Any version of flymod and any version of tech reborn causes this crash.

Can you try with just TR and the fly mod you are using? as this crash doesnt seem to have anything to do with either.

Closing as no response.
