Vanishing items

Psi

I have been collecting Mk3 Sienar Holo Projector salvage for a few days. I had 19/20 items. Today I collected the last one. When I went to craft, suddenly I had 1/20! I did not craft the item and I didn't use it.

Arghhh????!!!!

Baal

You crafted and used it.

Cestvel

Most likely on an other toon.
