So the two of us were going through Storage, and like usual I built my little barrier to hide behind at the top of the stairs near the rockfall for when the grunt spawned in that area later, and I advised my friend to do the same. So we continued on, picked up the rods, and I told her how we would have to sneak past the first grunt to get out. So I crouched just inside the door and waited for him to leave the room with the large torch in the center of the floor. I heard him hissing and such out there, and then he walked right into the room with me, something that he has never done before, saw me crouched there on the floor, and killed me. First time I have ever died in Storage.

After I had respawned, I was creeping along behind him, and we he went into the long room with the ledge running down the middle, I was expecting him to go left like he had in previous playthroughs, so I could go right. Instead he went right, and then turned around and walked right back into the room with me! Second time I have ever died in Storage.

Finally I got through the area where I had to blast the rock fall, and I crept up behind my barrier and waited for ugly to turn around so I could run past him. Instead he knocked my barrier over by walking into it and that was the third time I have ever died in Storage.

Oddly enough, he knocked my friend's barrier down too, but she was able to run and hide and he eventually despawned on her game, which I didn't think he did.

So much later, we were creeping through the Choir. Everything was going great, neither one of us had died or been spotted by Mr. Tall, and we had just left the second torture room and were heading over to the broken pillar to go across the chasm. I warned her that the brute was going to spawn once we turned the corner, and when he did, we ducked into hiding places to wait. He vanished in my game on short order. On hers, he stuck around for damn near ten minutes, before she was killed trying to get up on the pillar. When she respawned, he was gone, and she was able to get across.

After we had gotten through the final torture room, we were creeping along the wall to the chasm, where we were going to turn lefft and follow it to the bridge that was in front of the level exit. I made it to the chasm with no trouble. She practically ran into a brute's legs, and she was able to safely scramble behind a pillar, and he left the area shortly afterward.
