Just a small update, but not a happy one. I tried 'repairing' the game in Steam, but it found nothing wrong. Played a little bit, shutdown again. I uninstalled and reinstalled PoE, tried playing for a little bit again and crashed. It's weird though, I didn't have this problem in the beginning of the game. Story-wise, I've just unlocked the Stronghold and obtained the ranger, druid, and cipher companions and was heading towards Defiance Bay.
