Regarding not being able to run. I have come across this bug a few times myself now. Neither double tapping shift or holding it down will make my character run. I can go into the control options and am able to change the run key (shift is still able to be removed and added as the run key), but this makes no difference. I'm running version 1.7.1.5:93825. I finally got my dream weapon setup of a crossbow (plenty of bolts) and an m1911 with clips galore. Aggro some zombies accidentally only to find that I'm no longer able to run. Cue sadface del pablocampy. I've also run into the unable to lean bug too. For example, right now I've just spawned again (due to the aforementioned running bug) and I am unable to lean. I am able to run at this point so I don't know if these are related. Rocket, I believe you mentioned that you had you were unable to have zombies only investigating noise to walk instead of run due to performance issues? Is this the case, how are zombies able to walk towards other noise sources such as flares without this performance hit? Very much enjoying this latest build. My personal feeling is that the zombie hearing/vision balance is excellent. The 50% reduction through wall/environment can only make this more realistic and enjoyable. Will the 50% reductions stack? So multiple house walls between a character and a zombie will all but muffle the noise they are making? Edit: Also, as I mentioned I've just spawned. I alt tabbed back in to find my dude passed out with a very slow timer. [sTEALTH UPDATE] - Epilepsy?
