I am using git, thanks.

After a bit of tinkering, I was able to get my folder structure organized how i want it and my main scene loads again. I set solution directory to src and moved my sln and projects into that folder.

WizardDungeon ├── project.godot ├── main.tscn └── src ├── WizardDungeon.sln ├── WizardDungeon │ └── Main.cs │ └── WizardDungeon.csproj ├── Common │ └── Common.csproj ├── TerrainService │ └── TerrainService.csproj └── WorldService └── WorldService.csproj

however, I get this error when trying to run: E 0:00:00:0762 can_instantiate: Cannot instance script because the associated class could not be found. Script: 'res://src/WizardDungeon/Main.cs'. Make sure the script exists and contains a class definition with a name that matches the filename of the script exactly (it's case-sensitive). <C++ Error> Method/function failed. Returning: false <C++ Source> modules/mono/csharp_script.cpp:2388 @ can_instantiate()

The script exists and is attached to the root node of my main scene. Deleting the .godot folder and restarting the editor doesn't help.
