I often seen these games with one free spot but unable (failed) to join. I have also been in games where a player was kicked and nobody was comming in for the free slot. So putting the 2 togeter, is kicking a player bugging the room? *Edit* Player max size does not seem to make a difference to my expirience.
There is still some sort of bug with the 10th player joining. Quite often I find the 10th player takes an unusually long time to join.
