When I overlap a single unlock button (to select a character) with a navigation button that starts the game, sometimes only the navigation button gets pressed and the character is not selected. My game uses different characters for different worlds, and this glitch causes the wrong characters to be played on the wrong worlds. The buttons are the same size with “block touch through” not checked. They are perfectly overlapped. This only started happening recently and I’m not sure what’s causing this...
try make sure your navigation button is under the unlock button, if it isn't . see if that is the problem.
