the overlay colors not working i tried using mapster and it worked but i rly dont like that addon

It was actually an issue with the config not setting the DB var properly. It has been fixed in version 4.2.0 and is working properly.

This is a known problem. Not sure if there is a way to fix it.

Since Mapster can do it, there is without a doubt at least one way to fix it. I am sadly not lua-savvy enough to propose a solution.
