yes. the -servermod doesn't really seem to work. For my (tiny private) server i've set verifysignaturs to 0 and hope for fixes from any direction.

Setting verifysignaturs to 0 causing a different problem. Cars are going creazy when you drive them and hit box while u shooting is broken. Can take even a 10 bullets to kill zeds (head shots), so dont change verifysignaturs to 0 cuz its not gonna help with anything and only make it worste.

Well we have to do something, all of my admins and players are getting kicked when logging in. The only thing working is setting the verify to 0. From our testing last night we only got the PBO error with this mod. Other mods worked fine. I hope the mod author can provide us server owners with some type of working fix or someone can provide us with a solution that does not require a complete server wipe and changing the verify to another number. I have read the about this here: https://steamhost.cn/steamcommunity_com/app/221100/discussions/0/1646544348824177142/
The players were getting kicked because they are using DZSA Launcher, and that loads up all mods. Thanks hope something can be published on the mod page about this for a simple fix.

Lurking...

I've had the same problem with my private little server.
I've even tried wiping and re-installing everything, both serverside, and clientside on two different computers.

It's not any of them; so i reckcon there has to be some sort of incompatability somewhere.

For me its @CF thats the issue as thats the only mod Im running and getting the pbo issue.. over and over ive tried everything, now im a little annoyed and all these mods dependencies.

Here's my take on this situation after thinking it over a little bit. There are two different download sites, the steam workshop, and github. I believe that the github pbo file may differ in some slight way that isn't registered from the steam one, therefore, if you just take the pbo files from the steam workshop version and put them into the serverside client, maybe that will solve it.

Ive tried to see if I can fix it but I can not

I tried doing that pbo thing but it didnt work
