Just adding up, I got this same 3rd bug where u couldn't talk to anyone, however, since I could still do the quests, I decided to keep moving forward, then I reached the quest from the ship engineer of ensis, where you have to go to 1 floor below and kill that purple humanoid experiment to get the corrupted heart, however, after killing him i spotted that the floor below that one, that were on the previous version locked with a chained red cube like thing, was open, so i tried to go below which failed and triggered an array out of bounds expection, so i gave up and tried to climb up the stair to deliver the quest, but this also triggered the same exception, I found myself locked there and tried to load the game again, which didn't work and triggered the same error and also keep loading forever
