Eridian chests empty

So I am playing with my GF lvl. 50 in cooperation. When we open the Eridium break chest, there are items randomly only for one of us. Other loot systems work fine.

Everyone else having this issue?

Hey my husband and I have the same issue… we are trying to figure out if this is a glitch or not.

Actually it is not happening anymore to us. It looks like that this bug is not reappearing after game restart.

Although the system of loot is a real riddle for me. I thought, that if one player opens any box, there is also loot for the other one. But according to our yesterday gameplay in Jacobs Estate it looks like, that if one player is not close enough to the other, this doesnt work and the chest is empty.
