If that's the case, and you're using dplay_localfunction = 2, I'd suggest remove it. Its complicated for debugging and you can easily confuse whats running where, after your code gets more than 10kb in size.

If you're using the regular MP, its fine if you remove an entity from one machine...It doesn't affect the other machines...or at least I remember being that way. Cant test right now laugh

PS.: I just posted my MP tutorial. If you need some info, here's the link:
