I loaded the main file tho, and most of the old world is still there, because I don't know a way to quickly delete it all, I guess that's my main problem atm. I am thinking of just barricading off an area with some really tall mountains so that you can't go out, but do you know of a way to quickly delete everything in most exterior cells? I just want to keep some few and it would look a bit weird if the story happens in a barrikated area and you can clearly see there are more landmasses on the map. I did try to mark all cells and hit delete, but then it just appears an *D beside their name and they are still there and everything in them also. I want to drastically reduce the landmass so I just have a much smaller isle than entire Vvardenfell. Then I would have a much more realistic barricade, the ocean. The only way I know to do that now is to take every single cell one by one and delete every objekt in them and then use the landscape tool to lower the land a small part at a time and that would take forever.

I guess it's not a TC now because the world is still there and you could load an old save and do all old quests, but that's what I want to change now.
