The "type" icons on some adventures no longer match the "Type" info in details.
Dark Priests, historically an Experience Adv, shows a "Mini" icon:
And "Type: Experience"
Stealing From the Rich, another standard Experience adv, has a "Resource" icon:
And also "Type: Experience"
There may be others but these two are currently throwing off Christmas quests to "complete an Experience adventure" as the game is recognising the Icon info rather than the details.
If this is an intended change the Details need to be changed as well. If it's not then the all powerful icons should be fixed.
