I had an item go "missing". Just after the 3-4-10 patch, I logged into the game to play Infected. When I beamed down to the starbase with my team, I encountered that high lag long loading screen where I got the "Game will run at reduced textures" notice. When I beamed down I noticed that pressing Z wasn't switching my weapons, so I checked my inventory and saw that my Antiproton Split Beam Mk X turned into a second Antiproton Stun Pistol Mk X. Now I have TWO antiproton stun pistols, and my split beam is GONE. This is the weapon I bought with my exploration daily missions and the PRIMARY weapon I use on the ground. Does this affect gameplay? YES. I should either be reimbursed the item or the badges.
I CANNOT get a GM to help me AT ALL as they say it is a bug and that I will have to wait until the bug team fixes it. I have submitted two GM tickets without help. I CANNOT get the bug team to help me, I have submitted two bug reports and they tell me that a GM is the only person that can assist with individual cases of missing items.
I believe this is a known bug. If it is the bug I recall they have no way to prove that you had said item so there will be no replacement. I am sure this issues was discussed elsewhere in this section.
I'll tell you why it's important. The next time it happens, with the weapon I buy using raid medals, or with the weapon that drops from a raid boss that I win the NEED roll on, and nothing is done about it, I'm done. I consider items vanishing a major bug. That is why I am saying they need to work on fixing this now, sooner rather than later.
