The way you answer shows me, that you either didn‘t take a closer look on the mangos source code or you are using a fully compiled repack.
I can tell you again, everything in mangos is open source. If there is a bug that you want to fix, there are some tutorials in this forum and the internet, how to fix stuff in database, c++ core and scripts.
And if you think a little more about your attack distance bug, it may occur to you, that this has something to do with movement calculation for npcs, which is calculated using the variable.
If you admit, that you are not able to fix things, you can always add bugs to the mangos bugtracker on this website. The „secret society“ developers will maybe try to fix it in their „secret precompiled“ code…
In the meantime you should try to be a little more respectful. Mangos is the work of many people using their freetime to get an keep things running.
