Like Taika said, we had an issue or two during coil 1 and immediately made sure that it would never happen again. Yes, it sucks to happen and SE should get this fixed, but it's up to your group to make sure items are going in the right places. We generally have someone who constantly makes sure people are lotting/passing/staying in the instance and we haven't had a single problem since. Also, I noticed that resisting the urge to "LOT NAO" right after you open the coffers allows for people to make the right decisions.
