Root node gets replaced by empty Object

Animus_Surge

I'm having some troubles with the viewport for some reason.

As some quick context, the project in question is an auto updater for my game. It might have something to do with my game, but I can't be certain, because the debugger output doesn't have any paths that relate to my actual game.

What happens is when you run the game, it works as it's supposed to. It checks for updates on my database, and if there's either no version downloaded to the computer, or there is an update, it'll download it, then run the game. If not it'll simply run the game as normal (load the actual game's pck file in a bin directory in the user path). However, what happens is when the game loads the loading screen in the downloaded pck file, it gives the errors listed below and doesn't do anything else.

The system used to work, so I don't quite know what went wrong. I'll provide code as needed, because I don't know whats responsible for what yet. Here's what comes out of my debugger:

ERROR: getornull: Condition "!id_map.has(p_rid.get_data())" is true. Returned: __null
   At: ./core/rid.h:160
ERROR: viewport_set_size: Condition "!viewport" is true.
   At: servers/visual/visual_server_viewport.cpp:398
ERROR: getornull: Condition "!id_map.has(p_rid.get_data())" is true. Returned: __null

ERROR: viewport_set_global_canvas_transform: Condition "!viewport" is true.
   At: servers/visual/visual_server_viewport.cpp:616
ERROR: getornull: Condition "!id_map.has(p_rid.get_data())" is true. Returned: __null
   At: ./core/rid.h:160
ERROR: viewport_attach_to_screen: Condition "!viewport" is true.
   At: servers/visual/visual_server_viewport.cpp:436

There's also other errors that don't relate to this specific error, but they don't cause this problem. (They show up with this system no matter what)

Can someone please help me?

EDIT: Before I forget, I'm running Godot 3.2.3 stable on Windows 10

Welcome to the forums @Animus_Surge!

How are you changing scenes to the loading scene? Could something there be causing the issue, potentially? I have not tried something like this in Godot myself, though it sounds like a neat way to handle game updates! If it was working before I would look to see what may have changed. My guess is that something with how the scene is being loaded is the issue, given the problem seems to be a root viewport issue.

If you have source control (like git) for your project, something you may want to do is see if you can find a working commit and then work your way forward until you find the commit that introduces the issues.
