I'm very pleased that in my last 5 or so trades this week, I've not once had to close and re-invite to trade just cause the card list bunched up.
Maybe it's not that important to most people, but it was one of those things that was glaringly bugged. And when asked by a newbie what's happening, the answer would just be 'it's Infinity Wars (shrug)'. That kind of 'assumed permanency' of this being a broken game became ubiquitous amongst the playerbase, and imo it's a large part of what brought this game down.
And, for me, it seems to be finally fixed.
I posted this because I'm curious if anyone else has had the same luck. Also, maybe this could be a place to gather feedback about it.
