I am attempting to trade evolve my Haunter by dragging from one PKHex window to another. I am grabbing it from a Red save file window and dragging it to a Blue save file window and get thrown this error. I tried replicating by transferring other mons (eg. weedle, kadabra, machoke) but only happening on Haunter for some reason. Doesn't matter if I transfer to party or box. Does anyone have the knowhow to why this is happening? Error below:
