Didn't work for me, no
I'm running another conc map atm on my server and used your config and had no bags at all.
I tested your config on your demo map and there were no grens on that either.
If I can get that fixed, I'll run your map if thats ok? People really want conc maps at the moment, even basic ones.
Edit: Find me on IRC if you like, #playnice on Quakenet.
