v9.0b?I can confirm that the latest version of Monkey (v1.7.3.1) is working fine with SMA v9.0b.
All issues so far have been traced to incorrect installs. Please follow the mod instructions carefully.
In rare cases, Microsoft Defender in some eastern Europe countries will block all access to the game save folder (\Documents\TValle Games\Some Modeling Agency). Monkey needs READ access to be able to load save files.
If you are still experiencing issues, pm me.

Was it updated already? It says 9.0a on Patreon as well.
