myljach comments myself a problem in server of versus.
when it begins the map. The infected team can appear or attack without waiting to the readyup.
This is a error of steam or valve, creating bad the area of the starting point of battle.
This happens when a survivor is next to the room door.
I believe that they are in these three maps.
albert can fix this using the Stripper v1.2.2 with these files:
[You must be registered and logged in to see this link.]it is in a file rar c2m2_fairgrounds.cfg c2m3_coaster.cfg c6m3_port.cfg
you can use the files that are in server alServ2018 Coop in addons/stripper
