Hey, just a quick note to let you know this bug report wasn’t ignored, I reported it (as marked in the thread title). I’ve brought this back up with the team today to see if we can get it bumped up the to do list.
Very sorry about this.
In the mean time, restarting your game will reset the Troop filter. I know it’s really inconvenient, but I just want you to know there is something you can do to get around the issue in the meantime.
