Mostly yes, initially no. By checking .numties with .memloc/.memval or .tmemloc/.tmemval, they can find out if the bot is tied to by another already. Then they can try to find another bot to feed from. Unfortunatly there's still bound to be errors just because of the 1 cycle delay in information transfer.
Probably the best way to deal with this would be to use in/out set to the tier's age to tell younger bots they need to untie.
