I crated a new worldspace, basically a decent expanse of flat land covered with water (See: Ocean) over which i built a floating island castle.

When i tried teleporting to the castle platform i would just appear floating in the ocean, until i realised the castle is actualy at -190000 Z and the water level is -2000 Z. So i adjusted the water and land height to -200000 to save myself the trouble of moving 200+ kitpieces upwards for an hour. But now when i enter the worldspace, i appear on the platform as planned but can't move. I can't even move with noclip. Does anyone know what causes this?
