BE WARY HOWEVER, IF YOU ARE NOT 100% CLEAR ON THE INSTRUCTIONS, DO NOT FOLLOW THESE STEPS. In regedit you must only delete the files I have instructed you to delete, and take extreme care with accidental deletes of other files. If you still need help following this tutorial feel free to ask me in discord, my name is Lol_what3. Thank you

This is a relatively common issue, the imposter rom uploader caused loads of peoples games to automatically remove ROM if not from the workshop. The fix I figured out is to go to( on startup ) Go to search/type regedit/ The creative assembly / launcher /325610 / mods/ and delete that whole folder. If you havent already, before doing this go to the steam workshop and unsubscribe from all mods, and remove them from you attila data folder. ( do this before the steps I told you) This should completely remove the steam rom from your pc and fix the issue.

If somehow this problem persists you will have to wipe attila from your pc - First, delete total war attila from steam. Then delete it from your c drive by. program files x86/steam/steam apps/ common/ total war attila. once again go to regedit, creative assembly, and remove the total war attila files. Then finally, go to run, type %appdata% and find the creative assembly folder in that location, enter it and delete total war attila
Just wanted to post this solution I found here, it seems to be common and it would probably be good if someone posted it somewhere
Theres a few people on moddb forums asking about it
