As soon as you close the location hit next turn button on top right corner before rolling the die for loot. This will bypass the bug and let you procede.
Just finished Hook Mountain Scenario and all my characters got the rewards for specialization. Now I swapped out 4 characters and leaving 2 old ones and have been leveling up new members. Question: If I finish the Scenario with the new team on Heroic difficulty can I specialize the 4 new party members?
Thank you
