Whenever you get those error messages, you should click the "copy bbcode" button at the bottom of the screen, this will put the error log into your clipboard.
Then go to either the official discord, itch.io or even here on F95 and paste that log so Nunu can see it and fix the related bug.
The best place is discord because it has a channel dedicated to bug reports and Nunu is on the server almost everyday.
Well, the thing is I'm getting them at an unreasonable amount, like to an unplayable amount, which I highly doubt is actually the games fault.
Sometimes I get them after a scene ends, which then either skips the next time cycle, I get them when opening some of the "choices guide", also when I'm at the start and select which bonuses to have active for the girls all of them work fine except for Jenny, that one gives me an error which just leads me to a "You shouldn't be here" box which hardlocks me.
There's just so many, which seems more likely to be my save, not the game.
EDIT: Most have been resolved, just mainly the one I get at Jenny's menu when checking the reward tab.
