Updated script paths

[Remixful]

Godot version

3.3.4 stable

System information

Windows 10

Issue description

After I move a few files around (in the file explorer or the FileSystem tab in Godot), the script begins to throw an error that class_name already exists at the scripts new location. If I right click the script I currently have open that is throwing this error, and then copy script path, the path is the new location, so the script editor has the right file open. The only way to fix this is to restart Godot.

Steps to reproduce

1. Make a script, set a class_name
2. Move this script to a different folder
3. Wait for error to pop up (or soft-reload, CTRL+SHIFT+R)
