Playing the last scenario of pack 2 (with the clock tower).

 

Harsk is at the Waterfront location and encounters a Cultist. Since he has no weapons I am given a d6. I use a Blessing of the Gods from 2 other characters to give him two more d6. I then recharge Poog to add 3 to the check. Suddenly my dice are d4s. I cancel out of Poog and they remain d4s. I opened the drop down "check" menu to see if the d6 option was there but it wasn't.

Cancel and retry... if it displays erroneously, try turning the game off-on.

When you pulled down the "check" menu, did it say "Strength" or "Melee"?  (Or both, with d4s next to them?)
