+/- buttons not working in one save

[TheChronicR]

I have a rather bizarre problem. In my unofficial dynasty save file (the Pieces), +/- buttons on the keyboard are not working. If you don't know, these buttons zoom in/out and are quite important for making stories and taking screenshots. Their equivalents are working though. I have no problem zooming by pressing Z or X. But, you know, I prefer the old way. Is there a way to fix it? If not, I can go on with what I have, but it's quite disturbing. Note: the buttons work as supposed in my other saves. Thanks.

I've never used those buttons to zoom in or out, but if the buttons are working fine in other games, it sounds like a game glitch.  Have you tried exiting and restarting your game?  As you know, that fixes a lot of glitches.

Nevermind. A simple restart of the game and the computer fixed the problem.
