Playing a 5v5 Gap with random teams, the left side is all on team 1 and the right side is all FFA. EG, there are 6 teams, with the left 5 people on team 1, and the right 5 on 2,3,4,5,6.
Additionally, when trying to fix this by unlocking teams, there appears to be a limit to how many people can ally. Only four people could ally with each other, the fifth was left alone. Beyond the first four, the fifth player could not see any ally offers, and the four could not see his.
The "forever" file is too big to upload.
It worked before the latest update so I imagine the update caused the issue.
