"find items" missions bug

It happened alot of times already, and since the arks take 2 hours to answer your call, i didnt ever stay in mission long enough to get "helped"

Yesterday again, it happened (but it allways occur under the same circumstances) I was nearly at the end of the mission, killing everything before picking the item up, to be sure i would get the token. On one of the last mobs, i crashed...You know one of those "error, you have been disconnected" crap messages, and no-way to re-enter the game because "character is already logged in". Well, anyway, logging back, back in the mission : no more item! I saw it, passed next to it during the missions, but didnt pick up to clear all rooms before. Well, here i am, for the 3rd time : no reward, no cash, no token, after walking for half an hour to get to mission area, and another hour to clear it..

/me gets nervous
