Probably an edge situation, but here's what happened.
4 player game. 2 players started to play, 2 didn't place their troops.
After a turn, one more player started to play. The other one just chatted without joining the game.
Then the 3rd to join player disconnected and the game went nuts.
Yellows troops were placed quite randomly, he insisted he placed them elsewhere.
Turns started to end if no action was taken withtin 2-4 seconds (I assume this is important, since turns weren't skipped randomly but in time intervals). Also there was no troop placement at all unless you hurry.
My guess is it might have been influenced by players not entering the game instantly
That would be all.
