It looks like Constants broke the game (the very top error). I would recommend disabling Constants and trying again. I can't promise they are compatible.
Edit: The snailsbreeding issue is one that is fixed via the hotfix that I posted in the main post. Deactivate Aric's, drop that into your mansion file in appdata/strive/mods/arics/scripts, and reactivate Aric's. That should clear up the snailsbreeding issue until v0.9.5 is released.
The Constant's error should be resolved via the following - https://itch.io/post/1488530
