I am also having this issue. A zed will run up, swat once, and then just kinda sit there. An odd thing occurs with the runner zed animation. It sort of immediately transitions to an idle animation after swinging, if that helps at all. The walkers do a similar swing and a miss. Then they return to flailing about madly (love that) without doing any damage. Zeds are zero threat at this point, which makes me a tad depressed. I have not tried Ravage in MP, only SP as the above has done. I am also experiencing the issue of no sound. None of this was true yesterday when I first used the mod (March 14, 2018), but is true today. Was there an unpublished incremental update I'm unaware of? Yesterday zeds beat the snot out of me with embarrassing regularity.
Additionally, I have experienced the following with and without lots of different mods (CUP, RHS, Enhanced Movement, et al) and scenarios (many of which are made by fine folks whose names have popped up here, thank you all):
In every instance, loot seems exceedingly scarce for me. I do not know if this is intentional (given the default values in the module) or not, but even when I made my OWN Ravage scenario and bumped the numbers in the loot module, only 1 in every 15-20 "Press Space" objects actually produced loot for me. That being said, I am by no means a proficient modder (in fact, today was my first attempt and I did so after watching a couple of tutorials).
Any and all feedback is much appreciated. Finally, THANK YOU SO MUCH, Haleks, for giving me that "feeling" again. It's been a long time and is inimitable. I don't know what magic it is, but you've found it.
