[Tech] Game delay

This weekend numerous players are experiencing a huge server lag.  Our guns go through bullets in clip without actually firing any or firing them in spurts.  Shooting a rocket launcher became nearly impossible, I'll click the shoot button 10 times and no rocket fires.  When running in any direction our characters keep running in that direction sometimes long long after letting off the key, even trying to force them the other direction does nothing.  This game became unplayable when my gun refuses to fire and my character refuses to run and/or stop running.   I am not certain if this server just needs some refreshing or if some action was implemented to try to balance lag.  Whatever is going on...  not working at all.  instead of 100 people lagging.  500 people are unable to even play.

Same issue here and this delay is really anoying right now. My weapon cant fire while the ammo is running.

Moving your character with normal walk will make your character run into hordes of zombie it's really anoying when your playing Coop tho and the character wont follow the cursor.

It's unfortunate not many players are taking the time to complain on forums about this.  I was pretty positive this problem is so large that we need not give any info since you can experience it within 1 minute of gameplay.  If there is anything needed from the community to resolve this issue we would love to help.  We need some sort of communication about this issue as it's been longer than a week now.  I am rather disappointed that it has been this long and no one has even acknowledged the issue from staff as far as I can tell in forums or on discussions through steam.
