Issue description

In an exported Release file on Godot, if a TileMap node has a large number of tiles present in the scene, and a Camera2D node is present, upon calling get_tree().reload_current_scene(), the game has a chance of crashing without any errors, which can scale by the number of tiles present in the scene.

The game will not crash at all if get_tree().reload_current_scene() is called in debug mode.
This bug is not present in Godot 3.

Edit/Update:
The same outcome can be achieved if the Camera2D node is added after the scene is reloaded.
A workaround fix for this is having the Camera2D node exist outside the current scene.

The conditions for the bug:

• Running the game as a Release (not in debug)
• A Camera2D node is present
• A TileMap node is filled with a large number of tiles placed
• get_tree().reload_current_scene() is called

Expected outcome:

• get_tree().reload_current_scene() is called
• Game works as intended with no crashes

Current behavior:

• get_tree().reload_current_scene() is called
• There will always be a non-zero chance of the game crashing once called
• Otherwise, the game will continue normally until get_tree().reload_current_scene() is called again

There are no errors and nothing is reported upon crashing in both the editor and on the released game with the verbose console option enabled.

Steps to reproduce

• Create a Node2D scene
• Create a TileMap in the scene
• Assign the TileMap with a large number of tiles
• Add a Camera2D node
• Add a function anywhere that can call get_tree().reload_current_scene()
• Save the scene, assign the current scene as the Main Scene
• Export the project as Release
• Run the released program and call get_tree().reload_current_scene()

Minimal reproduction project

The provided project has a script that automatically runs get_tree().reload_current_scene() every 0.2 seconds, with the provided scene given to easily replicate the crash once exported.

Can you reproduce this when exporting the project with debugging enabled?

[fiaKaiera]

No, the crash does not happen at all when exported with debugging enabled.

Doesn't happen only with tiles, a large amount of Sprite2D nodes apparently suffices for this.
