It's not just the trader now. I had the game freeze during my tourney rounds, when trying to craft things in the MA and even when just opening messages. It doesn't happen every time so it's hard to pinpoint what triggers it. I've also had buildings go invisible lately. I'd upgrade them (or summon them) and they would be invisible for a few minutes then poof! they'd appear all of a sudden (actually "poof" is for things disappearing, I think, what's the opposite?
). The disappearing thing doesn't bother me much, just adding it to the list of bugs. Maybe the devs should take a 2 weeks beak from events (I'm pretty sure we'd survive just fine 2 weeks without events
) and fix the basic things first
