I'm the author of GetOffGetGoing (http://wowinterface.com/downloads/info5079-GetOffGetGoing.html) and I've found a bug of sorts that's related to mod interaction.
I was wondering why the fp's between Ogrila and Skettis weren't showing up for me. The localization was there, everything seemed to work...then it (haha) clicked. You're hooking GossipTitleButton_OnClick. Except with my mod, there's no clicking going on. Sure enough, I actually click on the option to start the flight and bam. There's an inflight bar. =)
I'm not entirely sure how to solve this. Any ideas?
