I like to use one single trooper's Eddie with no backups when I'm leveling up allies by playing (to get an exp bonus). Previous to yesterday's patch, it would leave the Eddie slot blank when replaying a certain level after using a trooper's Eddie with no backups. All I had to do was tap the next trooper Eddie, and go.
After the patch, it keeps defaulting to my personal last used Eddie when doing this. This is unneeded, as the game will not let you start a battle without an Eddie in the slot. It's a minor annoyance having to remove my own Eddie before selecting a trooper's Eddie each fight. If this could be changed back, it would be great. Thanks.
