Also the combine arent friendly to me i have no other npc addon

Interesting, considering this is a night level I wonder how well it would work. I'd imagine it wouldn't work very nicely with the rebel attack script, but I'll give this one a try and see if it breaks anything.

Darn, even after manually adding npc_citizen to the GarrysMod\garrysmod\data\stealth\npc.txt list, they still attacked on sight, without them being alerted. I'm not sure how I would be able to fix this without breaking the way rebels treat the player.

As for the issue with the combine still attacking, try disabling every other addon except for this map, and see if that resolves it. If it does, then some addon is messing with NPC logic. If it still isn't fixed, I'm not sure as to what would cause that, since I haven't been able to reproduce that issue, even though it's been reported multiple times.

Its fine im not gonna use it anyway after when on the map
