And then test your server 100 tick/nb_update_frequency 0.01.
Adjust z_resolve_zombie_collision_multiplie until zombies' behavior match almost the same as video
Nice! I just tested on my server 100 tick/nb_update_fequency 0.02 and setting z_resolve_zombie_collision_multiplier "0.25" made the zombie behavior closely match vanilla for me, thanks!
