I didn't save the game, but it's a fairly simple chain of events that I can describe in words:
1. Receive Gawin's quest, and go to the crocodiles. 2. Defeat the crocodiles and get the teleport gloves. 3. Test the teleport skill on the dead crocodile body (coz I wanna see the new animation) 4. Test the teleport skill on party member, finding that it no longer damages ally (I believe this is intentional?) 5. The party member that got teleported no longer follows the party when moving, as if they are unchained 6. When I switch control from the teleported member to another ally, the teleported member "reset" his location at the teleport landing position.
2nd issue: Getting into fort joy ghetto for the first time, and fight the thugs alongside NPC Ifan. Ifan, being a default wayfarer, has the marksman fang skill, which shoots through the thugs and hit Loshe. Loshe got aggro on me.
