I have a question about how the sniper bids work. I set up some earlier and it seems after every second bid that was not mine I would automatically bid 1 second after someone else bids and the time would increase to 1:20 instead of :50 like usual. For example jelli3108 bids at 9:55:32 the 30 seconds later wancman bids at 9:56:03 then I bid 1 second later at 9:56:04. I have seen this happen with other users but I have also watched long periods with bids only every 30 seconds. What causes this, is this how it should work?
