Pinhead camera bug (PC)
I've noticed a peculiar bug on Pinhead. To my knowledge, its been present in game for a few weeks now (3-4 to be exact). It occurs while using Summons of Pain and its not very consistent. Sometimes it does not occur at all. I think it has something to do with obstacles on the way to the portal. After releasing m2 button camera starts facing to the right or to the left and turns straight again. It really messes with vestibular apparatus to the point that i get motion sick after 10 minutes of playing Pinhead. Here are some examples of this bug.
I hope that i provided maximum useful data :)
