I am having a bit of a different issue but it’s bothering me too.
I have a 3rd party KLAX airport (inibuilds) but it will not load in 1.33.3.0 (the AAU2 beta) - I went to my content manager, the asobo KLAX is not installed, the inibuilds shows installed, but the airport is NOT loading.
Driving me insane.
