~So whats SUPPOSED to happen is you load in at level 1 with zero money (beli) and you need to get 200 exp to level up. This is what happens for me and it works fine.

~However, for my friends, it spawns them in at level 0, they have zero money (beli) and they need to collect 100 exp. The MAIN PROBLEM HOWEVER is that every time they level up they KEEP 100 exp.

------EXAMPLE: Say I am my friend who is level 0 and needs to collect 100 exp. I complete my quest that gives me 100 exp. I should now be at 0/200 exp for my total number of points and level 1. However it makes it so after I level it's 100/200.(if i level again it would be 100/300 if i got another 100 exp). Ik it's confusing im trying but if you have a solution it would be very appreciated. Thx.

This happened to me if you are using team create there is something called collaborative editing when 1 players are editing in the same studio you have to commit your scripts so you would go to view and click on your drafts and commit it so it will work in actual game if this helps please accept
