that bear avatar of yours is really getting on you mate ;)
commenting on your suggestion,I don't think that self bid should be removed.It's like a last minute attempt by the manager to get his player back far maybe any reason.plus that transfer is counted as a recent move of that player so if the manager puts the player back on the TL,he won't be receiving the similar %age of the price which he would have received earlier.
I agree with your suggestion to have a confirmatory question whether you want to recruit the player in the NT or not.
