I have weird problem with custom worldspace weather/sky that use Aurora (nif) "always visible".

When I enter my worldspace in game, everything is ok, but when I use ude some door that leads to another custom worldspace with different Weather and climate somehow aurora sky from first worldspace shows into another, without change. Then I save game, exit game, and when i load game into second worldspace aurora works fine, but when i enter the first one same problem. Somehow aurora won't change when i enter from one worldspace to another. Does someone know how to fix this?
