I posted this on my FB, but still want to repost it here. Unfortunately, when this happened last night I was in sleep so did not see how many rounds.
Last night, a crazy biding war happened on one of my players on auction but I was in sleep; look at the price in the red circle, which is 311M. The original price of this player is 104M. He is a AML/AMC/AMR with shadow striker SA and one point shy of 6 star.
I don't know how many bidding rounds happened but this must be extremely crazy!
