Treasure Chest in Brayflox HM

[CodeCass]

So just a curious observation:

So quick backstory: the first time I ran Brayflox HM, the party grabbed every chest on the way to the final boss. Well I died at the very end of the boss fight, and accidently ported back to the beginning. Well after shortcutting back, I noticed a chest that no one had grabbed. It's very close the cave entrance of the final boss in a little campsite. Inside was a Darklight Band of Casting. Score for my SMN! And of course since I was the only one left in the dungeon as everyone else had left, it automatically went to me. So the next time I ran the dungeon with a DF group I purposely waited after everyone left and went back to the same chest (I couldn't remember if we'd opened it on the run or not) and lo and behold, it was unopened and I got a Darklight Band of Healing!

I've run the dungeon twice more and every time, every group bypasses the chest, and if I wait until everyone leaves, I'm always guaranteed to run back and claim the treasure, which has always been a good piece of gear (things I can use and also some I can't).

So my question is: Is this chest just that unknown, or are folks running past it on purpose? Also these haven't been speed-run groups.

Just very curious
