Hello, I have had problems with the editor in that when i generate new terrain, the option for structures won't open and therefore I can't have any pre-built structures for said terrain and map. I would be very thankful for any ideas on how to troubleshoot said problem. Thank you!

I think this is what I mean. When you click generate new terrain and it says random sites, the box has a scroll down but it let me so I was wondering about that
