Seriously, L4d. Stop playing!

Okay stop messing with me, now! After hours of trying to get the saftey first achievement (no friendly fire damage), I thought I finally managed to get it. I would always get to the finale and acidentally hit someone with a pipe bomb, then have to restart. So finally, I beat the finale with no friendly fire damage. I get on the helicopter and it flies away. I still don't get it!? So I waited for the credits to roll to see if I really did hit a teammate, and it said 0 friendly fire incidents for everyone! I was so pissed! I got ripped off! Anyone else have this problem, or know how to fix it?

I don't know, seems like some of them don't register. My friend hadn't beaten death toll yet. When we finally did, he didn't get it. And he was in the game from the beginning without idling or jumping in and out. As for safety first, i always get to the credits and see i had one incident and I'm like "son of a Bitch!!!"

If the server used has some mods in it, then they won't register. It has to be a pure server as far as I know...

But that's only speculation. I've gotten all the achievements I've been "completing" with no problems on my server.

I did it with 3 bots in a server, so there is no way anyone got hit.
