So, I have no idea -how-, but, I'd previously placed an extra level down in my house (whilst having build mode on) then proceeded to go into it. Then I decided to go back into it to make sure the up/down style was correct...and I got black screen'd. Nothing I did seemed to fix it, so, I relogged. Then when I logged back in, I was back in the starter area.

Simply put, the problem seems to be with extra levels.

EDIT: After some testing, I've narrowed it down to the issue being exclusive to the one specific Extra Level I'd been using. I used the other spare one I had, and it worked fine in the same position. Yet no matter where it's placed, whenever I try to leave the extra level in question, it will send me to that black screen.

For reference, said extra level used to be used in a house I'd built before I decided to move to a portal house (having grabbed everything beforehand in order to remake it entirely). I'm thinking the issue may lie there?
