I know this isn't a bug but you legit have a feedback website with no section where people can give suggestions on how to improve the game... The purpose of this is to question why the heck you've made it impossible to build in so many places on official servers. All I've ever played is modded and they've made it possible to build to properly block off windows and areas that aren't completely flat or have no obstacles in the way... Like come on, this really does limit and affect everyone playing official trying to build a base. Definitely something you should change.
