My last playthrough I chose to attack Grove with Minthara;
When Minthara tried to murder my character we ended up in combat. After I defeated her I went to kill Ethel.After defeating Ethel I camped and was attacked by a vengeful Haslin who had managed to escape Goblin encampment on his own.
After defeating Halsin I decided to finish off the Goblins which went fine. However Volo was no where to be found. During my next long rest Volo appeared at my camp. When I started dialogue we were at the camp but he was in his cage (magically transported to my camp????). Ok no problem I'll let him out so we can trade. However I get no options to pick the cage door or use the key I acquired at the Goblin encampment so Volo and I are stuck in an endless loop.
