I make to you an example.

I am in the bid against another manager. I usually make the offer at the last second. In this way the counter restart from 60/30/20 secs (it depends from the bid stage). In the last times, when the other manager make the counter doesn't restart and in this way the bid is closed even if I have other token and money to make the next offer.

In my opinion someone use tricks to stop the counter, but I consider it not correct.
