As the game was set up the 6th player was vonluck. He selected a purple colour. That is still what shows in the status page.
In the game however the 6th position is white, the same colour as position 1 (mine) That would be tricky if we came in contact, BUT Amazingly, I can play position 6 as well as position 1.
I'm aware that sometimes a players may play 2 IDs. I don't do that, but here is something very strange. Without trying, I am controlling start position 1 and 6?
I've noticed it is possible for 2 players to choose the same colour in other games eg. chunks_59Ceilpry_514224 but both can play normally.
PS. I play only on my ipad 3 now.
