I searched for this issue and did not find it so here goes. I have found that if my pack is not full on log out that the gear will rearrange it self in such a manner that causes the possibility of loss of gear. For instance, I had a child brief case with two yellow protective cases and a few other items. I log out, come back the next day and one yellow case moved so that there is no more room for the other yellow case, which is no where to be found. I've had this happen with a sawed off getting bumped out too.
