Currently it is possible to boost the bids counter in the staff menue by making a offer and canceling it, then redoing the offer and so on. I do not see why you would want to do that, but still it should not be possible. It is also rather just not implemented than being a bug, but I wanted to report it anyways :) Cheers ^^

Could be abused to hide decent coaches from getting bids (a lot of people filter by 0 or low bids when looking for an easy coach)
