Twice today I have been bidding on players and been through several rounds. Then for some strange reason the bidding button has gone from green to white and I have been unable to progress to the next round. I have had tokens and cash available so I see no reason from that side of things and the internet connection has been fine. It's rather frustrating to use tokens to progress through the rounds and then the ability to bid is taken away, so I've lost tokens for nothing. Has anyone else suffered these problems?
