Jamba 0.5b released. I've fixed the quest reward lua error. Everything seems to be working now with the quests. There was a problem with the auto select and auto complete which I have fixed as well.

Jamba Proc no longer sends messages, but shows timer bars. Its a work in progress. Currently there is a bug with an Blizzards Combat Log api function where they are not returning proc information. MSBT is affected amongst other addons, and Mik has posted on the official forums with a bug report, so its wait and see if Blizzard fix the problem. FWIW, Paladins Art of War works really well.
