First I queued up units to be bought. Then I clicked for them to be bought for a player (rather than confirming the group), and bought the nonexistent group for the player. Realizing my mistake, I tried to create a group and noticed I had two groups for some bizarre reason. I tried to delete one but it's not responding.
Note: I'm on a connection with high latency, if that would mean anything.
