Vault 88 City Plan Question

I've tried googling/youtubing this question for the past 30 minutes and haven't had much luck. I just placed the Vault 88 city plan and it says it's 6 settlers. Does this get bigger as it levels up? Or should I just build it from scratch myself. I can't seem to find anything that shows a level 3 build of the thing. Thanks in advance!

Edit: Also, the front of my vault is glitched where there is no collision, so I can't put down anything for defense up there. Anyone else run into this before???

The max population in most city plans will grow as you progress through the levels. It usually only gets to a max of 15 but vault 88 may go up to 20. No idea on the collision issue.

for the collision issue are you running any scrap mods? in some areas, if you run a scrap mod it has an effect on the floor where almost everything passes through it as if its not there.
if you are running scrap mods, the only solution i know, is to remove them, which could lead to other issues as you don't want to remove mods from an active play through.

No, no scrap mods. I ran those once and the game eventually bricked itself. I've made it a point not to run those since then.

If the size gets larger, I may just let sim settlements build the vault itself. I've never ran into the collision issue before, so I wasn't sure what was going on at first. I thought about downloading place anywhere, but I really don't want to add any more mods. I'm not running a lot, compared to most, but I generally have bad luck with CTD issues.

place everywhere is a brilliant and very stable mod and would not cause you issues.
i'm interested in this collision issue though as my only recollection is that i hit it when i used to run scrap mods. once i removed them, those issues went away. Does it persist if you exit the game and reload?

Yea, it stuck around. I ended up just using the sim settlement city plan. Only issue with that though, is it seems to always be one bed short and I don't know why. When I had 6 people, I only had 5 beds. I've got 8 now, only have 7. Don't want to add to the settlement until it reaches level 3 though. I do have one room that appears to be missing a bed. I tried refreshing the settlement, but the bed never appeared. It's a prebuild room with a hovering pillow and book, so maybe something went wrong. Won't mess with it until later though.

I've never had collision issues before here, but everything I read was due to scrapping mods as well. Since I'm not running any, I have no idea what it could be. I'm just running player/npc appearance stuff and the stuff for sim settlements. That's it. So I'm puzzled...

Huh... I've got collision issues in the Mechanist lair too. No idea why. I may just have to get place anywhere. :\

Update: Place anywhere is the best thing since slice bread and I don't know how I lived without it. That is all.

Yeah once you have built with place anywhere you will never be able to look at the basic build limitation "menu" again without a curse to the dev team.
