I've encountered this situation twice now:

 

In the Heroic version of Approach To Thistletop, I encountered the Goblin Warchanter.  The app rolls 2d4 to add to the difficulty to defeat (scenario power). Then, both characters roll their Wisdom 8 check.  After that's done, the Goblin Warchanter (conveniently for me) forgets about the 2d4 it rolled, and its only a difficulty 8 check (or 10, at the Goblin Fortress). 

 

The first time it happened, I figured I just missed something. The second time, I was pretty sure it was a bug. 

Smells like a bug to me. Goblin Warchanter is my least favorite card in this game, but at least this is a bug in favor of the player! Silver lining!

It just happened again (I *really* need to win this scenario already!), and I took a screenshot this time (https://imgur.com/sGGjV0b). On the left, you can see the rule that says he should be +2d4, but the difficulty is still only 8.

 

Like I said, it rolled the 2d4, but seems to have forgotten them by the time the 2 wisdom checks are done.  Hope this is enough info!

 

EDIT:  Goblin Cutpurse has the same issue: http://imgur.com/pGbiVJO (but I might win this time!).

 

EDIT 2: I won!

Maybe he rolled two 0s???

The Goblin Cutpurse shows a different Scenario rule (When you defeat a monster, roll 1d6 - on a 1, take 1 fire damage).

You're right, and I noticed that too late to take another screen shot. But both powers were in effect, I just had the wrong one selected. I think that rule might have been the Wildcard Power, but I don't remember anymore.

I've also had the goblin warchanter card visually disappear when switching back to it after rolling for the character who wasn't at the location.

I don't have a screenshot of it, but yep, I can confirm the Goblin Warchanter forgetting about its difficulty increase after the "before you act" check.

 

And I agree, he's absolutely among the most terrible cards in the game, up there with the Siren, Satyr, and all golems.
