Hey Roath.
The reason the bidding only went up 1 is because it uses an ebay-like system.
So when you bid after the first bid, you define what you will max "pay" and then it will keep you 1 over any other bidder until they top your max limit.
Say that you bid 200, someone bids 205 and you decide "ill not pay more than 500 for this", you bid 500 and the bot will say "bid of 206"
If the other guy then bids 300 it will say "bid of 301", it will keep like this until the other dude bids 501 or higher and he will win.
If you want a bid system where it retains entire bid values, im guessing you need a new bid command or bot
