I don't understand. So what is the bug?
They're low level loot if you break then in cyseal
I would think getting level 20 loot on level 3 (the level 8 may just be from higher level chests). I don't know if any chests from the legion camp are suppose to contain end game level loot, though (if deliberate, I'd think they should be unbreakable).
In an earlier version there was an issue where unopened containers brought to the End of Time would produce much better random loot, but that should have been fixed.
Yeah, it seems like it's pretty much fixed and only those chests escaped the fix
I've tried doing this again with locked cyseal chests, and the only other one affected by it was Pontius chest (i didn't kill him before breaking it though)
