I was practicing with basic bots and when checking the traveler I couldn't figure out how anyone could make the contract. This is what I found.
I've seen this among human players but this is the first time I've seen it work with robots.
Is this an upgrade? You can now claim when playing robots? And they'll accept the claim even if the contract is unmakeable?
It looks like someone has figured out how to exploit a bug in the old version of BBO (otherwise known as the Windows client).
We are not upgrading that program, but we may be able to block this problem on the server end.
Thanks for bringing this matter to our attention.
