Crash: Unlikely Heroes quest marker broken

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?
