First of all, I know this is a Steam-related issue but it also plays a role on the OOO side of things.
For reference: http://forums.steampowered.com/forums/showthread.php?t=2103255
After steam trading with materials, the receiver of materials, loses all their material and the amount is set to whatever they traded for. This has gone for over 24 hours now without any progression to resolving the issue and it's apparently still going on.
What is OOO doing about fixing this ill-judged jump into Steam trade? Are we going to get our materials back or let out the back door? Either answer is fine, just want to know.
Steam support have said this is a Spiral Knight issue for Three Rings to sort out so just thought I'd let you know in case you forgot.
