It seems that with no stability enabled, occasionally any change made to an entity on the building effected will cause the entire building's walls to break down to the foundations leaving windows, doors, other entities still in place.  I have had this happen on two different occasions. The first is when I added a single twig wall to the roof of the building, the entire building collapsed.  The second is when I used the "ent kill" command on a single generator and the entire building collapsed.  Please fix, I use this feature to make grand buildings for my players to explore and use, but I cannot be rebuilding the entire thing every time I want to add or remove something.

I'm having the same problem. 

Im having the same exact issues, It seems the stability doesnt work in zone manager, if you turn the stability off in the server CFG it works, but how ever i need stability on the server as its a survival 5x server. I just need a specific zone with it ignoring stability, if you build/remove anything it will cause the entire building to fall! Please fix this issue @K1lly0u 

same.

Same. I can't paste in my town

hello, no stability works fine for us. are u sure u dont give yourself ignore nostability permission or maybe u give yourself all permission with .* flag ?

I have tried giving myself no permissions at all. It's for sure a problem. Especially if you use the copy & Paste plugin to paste a structure. It will crumble even if u remove for an example a campfire. I added stability false to server cfg to check and it worked flawless. I just cant seem to get the Zone Manager stabily to work. Seems alot others have the same exact issue. 

I agree that something is definitely wrong. I can put a zone up around a small structure and not have any problems at all. Even if I use the no stability flag. But whenever I put up a zone around a large structure that actually needs the zone to keep it together I get NREs like crazy. The building crumbles to a certain point and I can't even rebuild the part that crumbled. The NREs will continue and the sever fps will tank. I am forced to undo the paste and delete the zone.

did you try pasting with the stability false  flag with copy paste.

Yes, I have tried pasting with the stability flag with Copy & Paste. Doesn't seem to make a difference. As Tater was saying, ANY large structure will crumble and continue to crumble if you try to fix what broke the first time.

If you go back on version and download it from Oxide it works fine. This was the only fix I could find.

The base I am pasting within the existing zone is a town structure that extends off of a harbor and is completely on top of the water.  I don't know if that is a part of the problem or not. Whenever I used a zone elsewhere on the map the zone worked fine, but as I said before, the other zones were added after I pasted the item and they weren't large enough to need the no stability flag enabled.

Thanks anw2331, I will give it a try.

built a huge structure in town,  placed a door and it all collapsed,  however windows, doors , locks and vending machines stayed.   

I have zones on both land and over some water - didn't matter collapsed
