I dropped a .50 beowolf on the LE901 lower into the game via the map editor to try as a alternate for one of my mercs, I decided not to go that way since it would mean more logistics and went to separate receiver, and when I did it gave an assertion error about the default attachment being unable to be placed back on the item. 5739 in items.cpp, I am deleting it and just moving on, but I thought it might indicate a bigger issue for some items.
