user3966: Why is the second bid of wallet 2 getting ignored when I test it like this? If the first transaction of wallet 2 was also valid, then the second suceeds. I'm just curious if this is somehow expected behaviour or if there is some faulty code on the contract.
Print 1: Tested transactions

Print 2: Trace of wallet 2

I expected too see any print related to the second bid at least, can't understand why that doesn't happen.

user2285: If I recall correctly there is some problem/bug in the playground, such that when a wallet/transaction fails, no more transactions from that wallet is accepted.
But as you noted when first bid is accepted, the next bid from wallet2 also works.
