Balloon Towers not updating...
Seeking assistants for the Asuran Catapult Project. Applicants will be tested for aerodynamics.
There are more than 30 balloons, so you don’t need every single one. Also, after you hit the achievement for 30, all of the chests (even the ones you haven’t opened) become unlootable and open.
Just noticed the balloon achievement isn’t updating for me either. I still only have 1 showing as visited, even though I’ve visited a few balloon towers.
