I seemed to have clicked the "spend exp" on HP link too fast, because my battle pet has -1313 exp right now. What should I do?

I believe if you file a ticket they can fix it?

: I made up the exp so it's not negative any more. I'd like this glitch patched up in the future, though.

I think there must be something wrong with the Spend Exp because I just spent a lot of experience points on a pet and not one of her stats changed. Well it started to work but took a very long time for the changes to show up.

That's normal. The pets page is actually on a slight cache now so changes will always take a bit to show up. I think it's only like five minutes though.

Thanks for the info. I've just never seen it take so long before though. Maybe the event is slowing things down.
