Recently completed MoL however the game crashed between the boss dying and looting the chest. When client started again the chest was still visible but I was unable to loot. I tried all the tricks but still could not loot. I was able to interact with the NPC and receive a coffer from them. But was still not able to loot from the chest. I realize that not much can be done in my case now, I'm hoping that you can look into this so it doesn't happen to anyone else in the future, however.
