I am getting the below message when I try to make a trade, the trade bar is still in my trading partners favor. I was not aware that this is a restriction. Is there a way around it if both parties are OK with it?

"The number of selections from one side may not exceed two more than the other."

I think that's new since the UI update. In general, it looks like people just throw in 7th round picks to balance it out. Example:

Old way: Player A traded for 1st, 2nd, 3rd, and 4th round picks
New way: Player A and a 7th round pick traded for 1st, 2nd, 3rd, and 4th round picks

Im fairly certain it was always no more than 2 extra.

Yup.

Shows what I know.
