I made a bid on a trade which expired 12 hours ago. But I can't do anything with the rune I bid. So, anyone knows how long you have to wait to be able to use the rune?
As I remember, it should be about 12h, but don't know how it is now with Owls. Or maybe it was 24hours.
It used to be after 12 hours. I do not think it has been changed. You should be able to enter the trade and cancel your bid, even if the trade has expired.
