Eh...I would've kept on them.
I had the same thing happen back in the day when ry'gorr armor took white shards as fuel. The game was horrible laggy that day, I crashed to character select in the middle of a combine, FINALLY got back into game, and everything was gone but there was no armor piece.
Needless to say, I was mortified as the person I was making it for wasn't at all happy.
So I petitioned, was told nothing could be done. Turns out that was a load of cockamamey. I had it escalated twice. 3 days later, the person had their armor in the overflow of their bag like it was magic.
If at first you don't succeed, keep in mind that GM's have bosses with better access to stuff.
