So after a while of not saving Coins in my game, I decided to save them using DataStore 2. I was already saving another currency so no big deal, should be easy. So in this game, you get usually 5 coins after every floor but I can't just make the data stores save with 5 more coins since sometimes you'd get more like a boss floor for example or anything else. So I need to do some math to get it to increment any Coins the player gets.
This is what I did. (You shouldn't require more code than this)

This should work (I think?) but it doesn't. I went from 90 coins to 100, (double coins gamepass, hence why I can't just say 5 coins) sounds good right? I leave the game, join back and I have 55 Coins???? Whaaaaaaat? How did I get from 100 (NewCoins) - 90 (OldCoins) = 10 (AddedCoins) to 55??? I cannot figure this out, so if you can help please help :)
