Yep. I've tried everything I can think of to make this work. I've tried every character with only these addons enabled (Pitbull and Rating Buster) and fresh SV and whenever Pitbull is enabled other tool tip info (Rating Buster, Tank Points, Auctioneer, etc) is gone.. except for ItemLevelDKP which still inserts its tooltip info fine. Nothing in bugsack either.
I am having this issue on two of my three chars. For my Shaman everything is working fine but for my Rogue and Warlock Pitbull just doesn't want to work with Rating Buster. I'm using AGUF for these two chars instead.
Why do you think this is related to rating buster? with rating buster disabled I still get no text in pitbull.
This is two seperate issues being discussed. The author of Rating Buster and Tank Points made a change earlier today to solve this issue. For some reason, PLAYER_LOGIN event was not triggering and TipHooker loaded during this event. He changed the tool tip to initialize during VARIABLES_LOADED.
For whatever it's worth I'm still curious what about Pitbbull is causing the PLAYER_LOGIN event to not trigger but at least everything seems to work with this change.
