So I was running around, and noticed that I had 3 empty slots on Page 1 of my inventory. How strange, I thought. I put stuff there that I don't use up so they fill that slot. I didn't make much of it, I moved 3 items over to cover those 3 slots, including a full stack of Cobalt Rivets (99) and a stack of Grade 4 Carbonized Matters (about 94?) and something else over to Page 1 to cover the empty spots. I move on.

A few moments later, I made some HQ items for a friend, traded it to him, and then I suddenly notice the first 6 slots of my Page 1 inventory are now empty. There is NO WAY these were single split items that got consumed, as at least 2 slots I knew for sure were stack items that I did not use up within the hour.

What the heck just happened to the items that disappeared in my inventory? I am 100% certain I did not discard/sell/throw them onto the retainer. I have checked my storage areas. It seems like I just lost these items to the thin air.

WTF.
