I honestly have no idea if this is the place that this goes, but I cannot find any other place where complaints go, so... I was going to the market to sell 1 block of iron. I decided to go to redmarket2, but when I right-clicked the sign, I placed the block of iron, it disappeared from my inventory, and didn't come back. When I went back to get it, it was gone. I figured that either someone stole it or it simply disappeared. Either way, I am pretty mad about my iron. I would very much like to get it back.
This is usually a client side glitch. The block will still be in your inventory but invisible to you. Just relog and it should be there. If not then you are welcome to file a bug report in that section of the forums. Locked
