Approaching the table on the raised platform near all the loot crates in Mannammu causes the game to crash. It happened to me every time I tried it.
Though the loot isn't part of the quest, killing Verethi here is part of the Fighter's guild questline.
Ho boy, I checked out the spot, and had 0 crash. But I'm pretty sure I know what is crashing you. It's actually a plate with bad collision, it caused Digital to go nuts while making the main quest, so I found it, and it was fixed by Ormin.

It goes in the following directory.
