I am in com5 and com7, I do not know about the other worlds, but I am having the same problem in both of the ones I am in. I go to bid on an item at the auction. Let's say cages for example. the price will say something like 401$. I will try and bid like 450$. My bid does not turn green, instead it will be red as if I am not the highest bidder. So I will try again at a higher price, sticking to my example, I may go as high as 1000$ before my bid turns green, telling me that I have the highest bid. Then I can edit my bid back to like 450$ and it is now green and if I win, I pay only 450$ instead of the 1000$ I had to bid first to get my bid to turn green. I do not know why the system will not take the 450$ at first and it getts annoying.
