i don’t understand how you manage to make house interiors outside the area of construction, but building outside of it is considered an exploit and is not allowed.
Player specifies it’s on a private server, there are admin commands and mods to allow this.
The anti-exploit features you are talking about are currently only on Testlive and aren’t being included in the next update at this time. There is a server setting to disable it all together, and it is off by default on private servers, even on Testlive (last I checked anyways).
