JavaScript Why is my first test good then my second goes bonkers

[Idle Commander - The Dev]

I have this battle game and the first time you click battle it goes really smooth and well and does everything needed but once I clicked the button again there is supposed to be a 3-4 second gap between all the attacks to each other but it does something like this (1 _ is a second an "at" is an attack don't mind the spaces).



at _ _ _ _ at _ _ at _ _ _ _ at _ at _ at _at _ at _ _ at ... you died or you win.



And it is not exactly that pattern it just does stuff randomly why?

Here is the demonstration video.
