This game is fundamentally broken in the raknet system
Openmp also has other weaknesses
This platform is dead.
If you want you can go play at MTA
And with a little work, gamemode can be converted with the help of a plugin to an MTA server
Not that complicated, I did it myself a few years ago
There are still people who insist on developing new platforms, I saw one that gives syncNPC which is very nice because even MTA didn't do it (it is not clear why it is easy and they have the knowledge for this and more..)
In this whole game it is not safe and the only way to be protected from RCE is to sit on a socket connection and look for bytes that are relevant to the exeute/dll loader code
But this can also be bypassed, in short the game is dead, the time will come to delete it
