SafeMoon fork problems with LP

Hey, welcome!

Great!

It seems like you created a deflationary token (burn a percentage on transfer), just like abcoathup mentioned before:

this can cause issues with use in other contracts such as: https://medium.com/balancer-protocol/incident-with-non-standard-erc20-deflationary-tokens-95a0f6d46dea

Also I recommend looking at Points to consider when creating a fungible token (ERC20, ERC777)

A little complex to find out why it does not work.
