0.7.4 doesn't seem to be working for me...
I tried to re-install the game but it didn't work...
Below is the RenPy error message:
I'm sorry, but an uncaught exception occurred.

Certainly. This is what I have here:

I might see the problem. I think you tried to install stuff from the previous patches like events. What I would do is to delete everything, reinstall the game then get the 0.7.4 patch. If you reinstall the game without deleting everything it would add all that stuff you have back in. Don't worry though, it will keep your saves.
Edit: This worked for me.
To confirm what @Illra said, the special holiday updates were branched off separately, meaning that content created for a holiday update would only exist for that particular version. Attempting to use a holiday-specific rpyc in a different version is not supported.
@Illra @ThePotatoGuy
Thanks! Everything seems to be in place now.
Also, just a side question here-- If I pissed Monika off by cheating tampering with chess save files and she took away the chess game, do I get banned from the chess game permanently?
@sunzhaoyu Not as I know of, I would assume that she would take it away temporary for a few days.
It is possible to lose chess permanently.
