i was bidding on a player in auction. nothing special, but one guy was bidding against me. the player was worth 1.25m i noticed the other guy had 1.64m in his bank so assumed he could only bid up to that then would not be able to afford him! wrong! he kept bidding up to 1.77m and i walked away. He won the auction even though he couldn't pay for him!!

How does this work?
