Well people on this page are saying the opposite (you being one of them but there was at least Scy too) so idk. I'd rather they still be tradable/sellable, still don't understand who the hell cares.
I'd echo the team's sentiments and rather they not be sold.
I agree it sucks that they're no longer tradeable, but that's something to lay at the feet of yoshiP and team for a solution.
