Apologies, I was busy today so had to leave soon after doing the trade between you and Abe so couldn't give more of an explanation. I originally thought that as Abe never had the two Billlie cards, another CT member may have started the trade by "double teaming" the trade together or else had internet issues thus couldn't complete the trade and inform another CT member that it was half done.
Once I had realised Abe never had the two cards though I had already completed the rest of it, so thought it best to keep the trade as is and suggest Abe never had the Billlie cards in case those cards + the Brave Girls ones needed to be swapped back.
Thankfully Nina sorted it out.
I needed to leave so wasn't able to respond to any replies about this trade myself, but thankfully you took care of it/understood my simplified explanation. Thanks Nina!
