What are you saying? If you aren't sending the files to clients in the SVN, then how is the auto-complete working?
Anyway, I don't have ULX installed on my client, only on the server, and the auto-complete is working now.
I noticed when I joined my server, it downloaded cleardecals_svn.lua.
I guess ULX automatically adds all files in ulx/modules/sh/ to the client download list..
Edit: Nevermind that first line, I think I understand what you're saying now.
