I was trying to sell the item baggy cardigan black for 500m and naturally someone offered to pay with a CS and I accepted, first trade was unsuccessful due to full USE tab that I had and so I made some space for the CS but after that the trade would just be unsuccessful everytime, tried relogging and reclienting and nothing worked, we tried trading the cs and then i would drop the item but even dropping it did not work and so i gave him his CS back and here I am posting about it, I can still wear the item, just unable to trade or drop it.
It sounds like it's bugged, and will have to be removed by an Admin once that happens we can issue a refund. I've left a note on the Admin's list for you! Hopefully it can be sorted out soon. Sorry for the inconvenience.
