Upon using my charm to gate back, I opened my m&p and saw I couldn't do any combines because all my suspensions and vials were gone. My money level was still decreased and my skorp poisons were partially depleted. I noticed on my duplication attempt that the 40 pots I bought were gone too.
Second try to duplicate this, I bought 20 vials and 20 suspensions, made a poison, applied it, gated, and voila ... I have 19 vials but no suspensions. So this time I only lost HALF of what I bought!
Kinda freaky, eh?

At first I thought maybe it had to do with tradeskilling, but all my skorp poison sacs were there and also the pots I bought were among the missing. So it has something to do with the server not recognizing I bought them? However, it didn't return my cash like it does when buying skills past the teaching cap (if you try to train up a tradeskill for example, it will "let" you train it, but then when you zone, all your money is back and your skill is back to where it was).
