Hello, first of all thank you for the plugin and the effort.

I have this issue since forever. 

I have the latest version of Vanish, always keeping everything updated.
Scientists in Military Tunnels, Oil Rigs and Cargo ships shoot at me regardless if im vanished or not.
Normal scientists on road loot however, doesn't shoot. 

What might be wrong? I want to resolve this once and for all.

Also, is it possible to make other players hear my voice through voice chat while im vanished?

Can you post a list of other plugins you are using? You probably have something interfering with vanish.

Seems like "DontTargetMe" is the only one related to this and might be a collision.
Plugin's code is : https://pastebin.com/mZZbDUTX
(I don't really know how to read it and resolve the collision if it's there)

Try unload don't target me and then see if vanish works

I didn't even know that I installed "Dont target me". Yes unloading it solved the problem. :)
Can you advise on the second question? 
(Also, is it possible to make other players hear my voice through voice chat while im vanished?)
