I have never heard of anything close to that happening. Are you using some kind of emulation software? or a mod of some kind?Well as you know, if you click the left mouse button (or press space/enter), it advances the conversations ...
Whenever i do that, instead of advancing the conversations/event/whatever, it goes backwards to the previous line instead of forwards.
At this moment, im stuck on the map screen. If i try to go to class and click to advance, it goes back to the map
Same thing happens when i go to patrol or other activities i can do. I cant progress in the game anymore. I've tried everything.
I dunno if i can explain this better
The only thing I can think of off the top of my head would be to redownload the game, extract it to a new folder, somewhere that is not a system folder, copy your saves and screenshots over, and try again.
If that doesn't do it, you might need to check for suck keys, maybe the mouse wheel is doing something, IDK, maybe try another mouse? Does the same thing happen when you use the arrows to highlight the option, and the enter key to choose the option?
