I am somewhat confused on the purpose of the mp_bin file.
In all my experience this method is 100% useless to place any files in the so called mp_bin pak. Some people say as long as mp_bin is done correctly, there is no need to run an unpure server. I will agree that there is no need to run an unpure server to get a mod to load, and as long as everything is done correctly it will automatically find it and load it.
Is it just me having some luck or something and never encountering any problems without ever using an mp_bin file, both on windows and linux (compiling on both, running on both), or is there some clients who can properly use the mod without the mp_bin file and some that cannot?
