From personal experience I realized that with any update it is better to start from the beginning, especially for rempy games because each time (broken or changed) scripts are saved and accumulate like a SNOWBALL and you can see bugs of varying degrees (cruelty), once I caught a bug that simply did not give me the opportunity to save, no matter what I did, the game simply refused to save the current progress. As a result - MINUS wasted hours of life, and the beginning of a new game -_- . Apparently the bug is rare, but very unpleasant.
I am still getting an error where the game cant find the AMI vorcha scenes. "img ami vor1 not found". I think it is with more enemies than just the vor
It's not possible for AMI to encounter the vorcha, because now she is available only for first POI with apes, varrens and rats. Maybe your save is broken.
