This just started happening in the past couple of days, don't know if it was because of an update or if my save is corrupted somehow? Steps to replicate:
1. Go to the world map
2. Click the 'unlikely heroes' challenge flag
3. Click 'Select Dungeon'
Unity player immediately locks up and stops responding.
I can however still select venture cave as normal - if I complete the quest this way (manually selecting the elven fighter characters) will it still count?
