I see people ranting about the change but there’s no threads titled with the solution.
You should still be able to put ladders on rocks, to counter "impossible’ rock bases. Player made buildings is fine though, to get rid of the Chinese style houses being thrown up these days. Simple solution, simple fix, simple post. Give it a shot rather than reverting back to where the rock bases were prominent back in the day. Hell try it for a week and see how it works out!
Rust for life.
