Reproduction:

The other day I stupidly opened up two lootboxes at the same time, and found out the hard way that they did not in fact stack, so I only got one item out of it and wasted the other 5k monkecoin, at least from what I remember I didn't SEE any second item nor could recover any from the esc menu.
Simple fix to this would be to prevent someone from opening a second lootbox if one is already being opened, something to that effect.
