it doesnt disable npc ai, it just adds the flag FL_FREEZE to entities put in, in case of players and npcs they should freeze, unless you have some addon or something else that overrides flags. using lock and freeze functions insteal would only work for players

any idea of mods that could do such a thing?

ULX, ULIB, TFA or any other major lua based addon or anything that does something remotely close to freezing or adding FL_ tags

maybe you didnt activate the chamber propery, you have to type in a number then hit enter with the bar selected

its working now, thanks
