THANK YOU GUYS SO MUCH!

This was absolutely the impression I was getting regarding the "voxels" because they just did not seem to want to budge sometimes...but other times I could get them exactly where I wanted them to do. I couldn't quite figure it out. Sounds like I still want to find the flatest possible area because it seems like it'll effect performance. And less work to do, of course. Sounds like making several buildings rather than one all-encompassing mega building would be the way to go.

I understand the raids now too. This is more of an event that can happen, not a constant deluge of monsters. That does make me significantly less worried! Thank you!
