Not sure if what I witnessed was even a (known) bug or not, but just in case: Some bunny seemed to be overloading the dropship by just dropping one bit of uranium into the wall behind the dotted line, picking it up and dropping it again into the wall, apparently duplicating uranium every time. The result looked like this
EDIT: then again, maybe what looked like picking up the same uranium was actually buying a new one and dropping it immediately. So it could have just been a buy-drop-repeat-loop. Still looked suspicious though.
