Okay so I finished a mission where I had two treasure hunters on. Mission rewards 150 gold. I use the Master Plan Add-On and at the end where it shows all items that you obtained from the missions it showed my gold count as 75 instead of 150.
Now I did not check my gold amount before completing the mission so I did not do an actual comparison to see if I did or did not get the full 150. Figure I'd just ask here if anyone knows if Treasure hunter stacking doesn't work or if the Master Plan UI is just bugged at the end for gold income from TH stacking?
Don't have any multi single follower mission that provides gold I can do to test. So until then I figured ill ask here and eee others responses.
