In the project https://github.com/z80/iland The problem shows up in the https://github.com/z80/iland/blob/master/project/game/state_main_menu.gd file at line #9 which is gettree().changescene( "res://menu/main_menu.tscn" )
For me it works only once. I.e. when in the beginning the Main Menu is created, everything is fine. But when I try to get back to Main Menu from being in a Level all I see is a grey screen.
The project is runnable with the exception of this annoying problem. If it matters, Godot version is "v3.2.1-stable-official".
I'd appreciate any help. Thank you!
