So as most of you are aware, by building a base on a rock, with no way up, right now, pretty much secures you. Unless you get caught off guard as you're placing or trying to dismantle the stairs to get up.
Building on top of rocks is not glitching at all...
To get inside your base by building a staircase then removing it... rather questionable but if the game allows it then so be it. ( pretty sure it won't be in the final version )
I've built on top of rocks but I always build a staircase up BUT I do not remove it or the structure around it, if someone wants to raid it " goodluck " who's bothered anyway ?
There's not much you can gain from raiding in experimental that you can't farm in 1 hour or less anyway.
