Having reverting to a load prior to purchasing the bakery it reinstated the bakery automatically, and set the game to the point of the mission where the bug happens. Also Opal that appears on the map that I had collected appear on the map but not in the game.

When following the additional Baker's quest from the home village the following storyline is followed:
Tarben (Guthban) is escorted to Whilf
Tarben supports you as you get the items in question from the camp
**Once the battle is over Tarben and the quest icon is off the world map and nowhere to be seen
Cannot return to Wilf to finish the quest

**Reload the game after shut down or standby mode (xbox) completion dialog of the battle restarts between Tarben and Eivor with only Eivor being heard the rest is stated in subtitles.
I've been playing for a couple days without being able to end the loop. The only way to go back would be maybe to return to a state 4 days prior.

**Bug issue
