Found an unintended effect. Since buildings aren't always totally capped with roof tiles, you can climb onto a roof with this mod, and fall down into the building. You can hop out the same way if you remember what tile you dropped in from.
I found this trying to open the back room door to the gun shop in West Point. This means you can get in and out of the gun shop without breaking in or needing any tools at all. So you can loot in total safety.
I bet there's nothing you can do about it since you'd have to check and fix every ceiling. It's not a serious issue, but it opens the game up to some serious cheese.
Also, if you did make zombies able to climb like someone suggested, zombies could pour into the middle of your house, spoiling this mod.

After more testing, it looks like you can climb up through a wall to a second story, if you climb diagonally at the corner of a tile.

This mod work fine on PC. But the only bug I know right now that it doesn't work on controller like steam deck or what ever. It would be really awesome if this was fix.

its not really working at all, i haven't touched the game in a while and that time it was working, but when i returned it wasn't working at all. i tried to climb empty handed, made sure i wasn't over weighted from my loot, changing the keybind, changing the keybind back, nothing is working so far.

@kev_cat maybe check what you changed.

how do i do?

On modded buildings you can climb to the second story even if theres a wall there

only modded?

I've found that for some reason, when walking through doors if you press E (To close the door) sometimes you can try to climb onto the roof, which can leave you stuck quite high up which can be very sucky

Hey, im using this mod on a multiplayer server with my friend and whenever we climb up on a roof, i cant see him but he can see me. its like hes still a floor down even when he climbs, cuz sometimes i can see him walking on the floor below me, although he say hes by my side...
can u check that out? thanks and great mod btw
