Not sure where to put this so I'll stick it here for now. In case people are unaware you can have a recently updated map play on a bot by using a saved game.
I was unaware of it myself and thought it worth sharing.
"By the way, I found a way to play lobby with the new map. Just load a saved game (from local play setup) with the new map and options loaded etc. You can’t select from the bot drop down menu like you said, but I was able to get my saved game onto the online lobby play."
