Sprite renderer problem

BBML

Hi!

I have two scenes a menu and the actual game. I have a game object called Background and I made it a prefab to use it in both scenes. I've put a script on Background which changes the sprite used for the background with a Sprite Renderer.

In the menu it works properly, but in the game scene I have a problem: I'm using game states and at void Start I change the game state to generating a grid.

Here's the grid generating script (boardPrefab is a Sprite Renderer):

And for some reason I just can't figure out why, sometimes the grid doesn't appear. With the first/default background it always works but if I change the background for some it doesn't show and it's random which ones. One time it worked perfectly all of a sudden without any change to any of the scripts but then it went back to being bad. Even if I build the game its bad for some themes. Please help, I need this for a school project and I just don't know why it's not working.

Some of you might recognise the script, yes yes it's not original work (at least the game manager script).

It has been solved!

The solution: So this was a 2D project and the Background game object was 10 on the z axis and the grid and everything else was on 0. I had to put the Background game object farther back on the z axis to be axact I put it on 100 and this solved my problem. (So it wasn't the sprite renderer)
