I humbly suggest you change the name of the game to Ally Merchants Of Heckfire, since you people clearly did some tinkering with the way the ally market works, and now buying back allies is literally all I do all day long on this game.
People have always bought allies, you probably now have a bunch of allies in the range where people are now searching. There will always be buyers and those who get their allies bought.
Welcome to every ATA game ever, ally market moves fast, nothing new, nothing wrong with it. The more expensive you purchase the longer you'll hold onto it
