So I made a raffle, just like any other day. Everything went smoothy. I got the trade offer, I accepted and it went through.
Immediately afterwards, I got a notification that I won a raffle. It said I won a vita-saw and a big earner. I accepted it.
When the trade offer was sent, it only included the vita-saw. I accepted it anyway, in the naive possibility the other weapon was going to be sent in a separate offer.
Then I checked the raffle.
It ended 1 year ago.
Then I realised that the vita-saw I gave away and the one I received might be the one and the same.
Soon enough, my raffle expired and the item didn't go through.
Here's a screenshot of my trade history to tie everything together:
I'm more amused than annoyed about this.
Also, there's no need to fix the raffle because you know, I got the item back... I think.
