some of the prefabs I have are effectively just worlds rather than objects, (lots of stuff scattered around the Plate or another map) but if I manually place them down I lose the position they had relative to the world spawn
(or the position relative to the house/peaks, or just how far off the ground they were)
I think there should either be a way to have the converter turn them into a world instead, or have the "My Worlds" menu show brz files that I placed in the worlds folder, or something.
Kinda like how I can currently it appears like you can currently do this with the "Downloaded Worlds" folder. But you actually can't, it just gets stuck loading eternally if you do that, so don't do that right now.
