Thanks but I figured it out. Forgot to change the names of the layers in the event sheet after I changed them in the layout screen..oops..
Just want to give a big thanks to the Construct Dev team, the latest update gave my game a huge performance boost. My game is running on my phone at a silky 60 fps steady, and that's with large sprites and large background objects that aren't even tiled! Thank ya, thank ya thank you!
