ls:WaitForChild("Coins"), Infinite yield?

So basically, I've been having an issue in my game, whenever I update it or something, the WaitForChild breaks? I change it and boom the waitforchild works again? But every time I update it it breaks again! Nothing in my game works including mining or the shop! Someone help!

Infinite yield means that the WaitForChild has exceeded 5 seconds, I believe. It probably means that Coins hasn't been found, so you might want to try checking if it's actually located inside ls.

Hope this helped
