but I have one problem.
I have 3% reflection in my contract. When I change the total supply by mint function, the reflection math gets messed up.
plz help me on this problem.
Thanks in advance.
nobody can help me? 
I personally avoid helping with anything Safemoon related. But if you want others in the community to help you should provide more detail about the problem: show the code, show the formulas, and how it gets messed up.
Avoid phrases like "plz help me", they make your post look less serious and will not get you any more replies!
