The title says pretty much everything, I can't find it!
The game has a zoom in and out function and the UI stays on the screen no matter what, but you can zoom in on this button, and the only other place for the location of that button to be is on the main scene but there's only a few things on there and I barely touched it while adding a new feature which is literally just a particle system that turns on and off based on a value.
My main scene is:
Node2d
--Tiles (Group Node)
--MouseFollower (KinematicBody2D)
------Camera2D
------Collision Shape
--RainParticles_001 (ParticleEmitter2D)
--Canvas Layer
------UIMain (Control Node)
I have no clue why this mystery button is here and only appears on screen when I run the game, this button does not have a texture and every other button I have in the game is textured.
Thanks in advance.
EDIT:
It is a demon button.
