Thank you very much for the solution Oleo!

I can confirm this. Just removed it as described by Oleo, restarted game and reloaded my previous posted 2 CTD-Files (Rome + Baktria).

With Oleo's solution, no CTD happened both times!

Instead I got in both cases a correctly rebelled (to Saka Rauka) Sulek with 11 Elite sauromatae fat aexsdzhytae only by removing its mercenary-trait. Perhaps its by the program not allowed, that mercenary-Units take control of a rebelling city?!

(If somebody wants it, i could provide screenshots or files for proof!)
