People are going to edit the core files anyway.
Falco thinks he’s might be able to save himself hassle by saying “DON’T EDIT THE CORE FILES!” but it won’t stop people trying to add him on Steam and asking him for coding help with DarkRP edits anyway.
It might sound cruel, but I prefer the approach of “you break it, you bought it”. Basically, if you’re editing it, don’t expect any assistance. Some help might be provided - but don’t expect any. Especially since the gamemode’s free and there’s enough documentation floating around.
It’s unfortunate that not everyone is able to understand how to fix certain things and that the creator doesn’t have the time to help absolutely everyone - but that’s life. Remember not to be a victim and use your own intellect to overcome challenges.
