I just put my first Dilithium for zen trade request in.... My dilithium is gone...... But the zen I attempted to buy with said dilithium never appeared.. So now I have no zen and no dilithium..

I admit I did try a low-ball offer for my dilithium 258 Di for 1 Zen to buy 225 zen... ( the current rate was 267) But still... If no one accepted my offer to buy, Shouldn't I still have my Di???
