We are a 32 person league. It is only the person that sends the trade that sees the "undefined" screen.
We have had luck making a "One trade at a time" policy and not letting someone submit the next trade until the two that just traded verified that they have cleared all trade related messages.
It doesn't always work though, right now we are getting the glitch after making everyone verify that they don't have any trade messages (this is not an easy thing to do and there is no way to ensure it's accuracy)
We think if we advance to next week with trades off and then turn them on again, it should work. It has in a previous week. Our advance is tonight, so I'll follow up with an edit after that.
Appreciate the time of the team, this really needs to get fixed along with the draft glitches and 32 user glitch (I hope to god you are aware of that one, there is a massive bug report going back to EARLY last year on that one)
The new upgrades really mean next nothing if we can't fundamentally run our leagues without fear of having to restart. I can't overstate how much manpower and frustration that causes to us CFM managers (and it's users)
