Drake, difficult to really know.
Worth trying.
Problem is, with the way DarkRP is coded, if you change it to only 'return', you may break it or other scripts.
Tip for all Gmod lua coders - returning anything, even 'true', breaks 99% of most Gmod standard hooks.
It will in most cases prevent any other hook of the same type in other scripts from running.
Yes, sometimes that is wanted (returning false, etc), but in most you don't.
There are exceptions to this rule of course, but, not many.
