untill a recent server change / reinstall the cloak guns worked fine / npcs couldnt see the admins and players didnt crash .
unfortunatly i wasnt around for the reinstall of fl which was done by one of our other admins so i dunno what was done.
I know there is a sequence in which the admin/lelos mods are installed on the clientside that effect the way it works(one overwrites the other ect) and actually causes the problem that i described but i have tested all these and it seems its ok.
Allso for what i remember the admin mod does not need to be installed serverside because an earlier admin had written the nessacary parts into the lelo mod and this was installed on the server as well.
