With the standard Garrison Missions UI (Draenor), Baganator's inventory tooltip works (for the rewards). However, with the Master Plan addon loaded, it doesn't.

Since Master Plan is such an essential addon for the Garrison, is there a chance that you add support for it?

As an aside, in the Shipyard UI, it doesn't work (with or without Master Plan).

There isn't. MasterPlan explicitly doesn't use the GameTooltip (which is what is supposed to be used), presumably to stop addons hooking in and adding their own information.

Reopened as I checked with the master plan author, its ok to add info to it

Try this Baganator-221-1-ga95933e.zip

Both are now fixed in the latest alphas

Yeah, just updated, works great with Master Plan now, even Shipyard 😃

Thanks, and special thanks for your extra effort ("checked with the master plan author")!

PS: Works also with Venture Plan now :)
