The entire reason I made this post is because I built a base in the vault and noticed that everytime a thief or hitman came down they'd try to lockpick the vault door, fail, and leave. Some of them would ask in chat what the vault code is. I'd reply, informing them how to find it. Out of the like 6 or 7 people that tried to raid me during my stay in the vault that single day, none of them bothered to try. That tells me that the vault door itself is a very strong defense against raiders, you add ontop the ability to build a base inside, that just seems unfair. Certainly an easy solution to make it more fair to raiders would be to just make the vault door lockpickable. Or, if the intention is to keep the vault code a unique feature that you're required to find, my suggestion is to add a restriction/limitation on how you can build in the vault to make it more fair. Or maybe it doesn't even have to go that far, maybe just a text screen explaining how to find the vault code may help players, but like others have said, that's still something people have to spend a couple minutes to find even to just have a chance at raiding.

Again Delete the entirety of the vault if you guys don't think we should be restricted from building in there other wise its a waste of loading time space. It was for a halloween event anyways which happens once a year it's a waste of space

Not with what I've experienced lmao majority of the day you guys are afk XD   You wouldn't be saying this if you actually took the time to build as many bases as I do lol  

I wouldn't want to make it more OP than it already is though... Thats kinda why I believe it shouldn't be a thing because of how OP it already is.   One point would be to have a fading door right on the inside of the door and then you have a party member run to your base when the raid initiates and close the door behind the raiders than there is no way for them to get out. They would have to suicide and lose any temp weapons that are on them.   I'm down to walk people through how to find the codes as thats what we did when we changed maps but when they change daily most people would more than likely !cancelhit and get a new one or just go find another base to raid since it could take nearly double the time to raid it since you have to find a code.    I wouldnt say remove the whole thing, it could be used as a place to keep a hidden code or store maybe a traveling NPC that moves around the map and if you find him you get a reward or something. but as a base it seems OP.
