I only offered the above deal to magracefan and never confirmed it. In fact, it still isn't even an eligible offer until AFTER Bernie makes a pick as it was conditional on my player being available.
By your logic, as soon as owner 1 sends an offer to owner 2, that serves as confirmation. This is not, nor has it ever been, the way trades are executed in WIS. It was merely an offer, not a binding agreement. The deal is never official until BOTH parties confirm on a trade thread.
