So I went on to work on my build today, and when I tried to mine/place blocks on my build, it wouldn't let me. Anyone know why?
I'll take a gander and say that you are builder I and that your project is in creative world. If this is the case, it was a bug that builder I had builder perms in creative world (/warp creative is builder II, /warp builder is builder I). If I'm correct, then find yourself a new spot in the builder world, then contact an admin to have your build moved over.
