Question Colliding gameObject stored in a variable turning null for no apparent reason (Fixed)

Hey! So I'm using a collider and store the colliding game object in a variable, which works and is never set back to null. But when I try to access it from the OnMouseUp Unity method it's always shown as null, same thing if I put it in a list: the list length will be 'magically' zero even though the events happend in the right order and the var is still not null..



I did a second test making sure I would never assign a null value, as you can see with the replaced line down below. And I printed the variable content on Update(). As you can see it alternates for some reason.



Any ideas? Thanks!

Edit: Turns out the issue was outside the code!
