I'm trying but can't find any permament fix. After I changed my cartographer and questie addons to latest ones, everything started to go wrong. I completly cleared my wow client (wtf, wdb, addons etc.) and it still happens, I can't understand that.
It also disappears after changing resolution. But I just need a relog or dismiss/call and it works again till I change resolution or do /rl again.
Same happens even on other hunter characters, tested it on TBC PTR realm and the same problem. I completly removed wow from my computer, did little clean and scan etc. downloaded client again from Nostalrius site and still the same. So what the hell is going on? Can anyone who play hunter and uses cartographer confirm that he can /reload and change resolution without bug with pet action bar disappearing?
I found this but no fix:
