Time.TimeScale = 0f stopped working to pause game. It somehow sets back to 1f, why? help please

Hello there, yesterday I was implementing a pause in my game, I followed some tutorial and everything was working fine. Game was pause when I hit escape and unpaused when I hit resume in my pause menu. Today it magically stopped working. I tried to debug it, but only thing I got is, that it somehow sets back to 1 after I set it to 0. Why? Can anybody please help me to solve this as I really want to pause my game? I attached link to my pausegame script. I really wonder what I did, that it stopped working. Can't figure it out. Thank you all for any help. I appreciate it.

Nevermind. Got it working. Hint for future developers. Take care, where else you play with Time.TimeScale values. I had another script for game over menu, where I had an else statement in Update() method, which was setting Time.TimeScale back to 1. Fixed!
