Hey I'm a longtime TES player and only recently started doing the Creation Kit tutorial provided by Bethesda. I've succesfully created my dungeon and linked it to the Tamriel worldspace as specified in the tutorial but I've run into a strange issue. When I exit my dungeon after loading save the dungeon entrance has missing architecture, if I re-enter the dungeon and go back out everything works fine though. Here are the ways to cause the issue

-Load inside dungeon, go outside. pieces go missing
-Load in unrelated area, Whiterun was used here, fast travel to dungeon, pieces go missing
-Anytime pieces are missing, entering the dungeon and going outside causes them to appear.

The entrance made of several pieces on the static Nord dungeon exterior set(identical to the Beth tutorial). Several pieces go missing and I'm left with a door and a few banners floating in the air. I tested the behaviour by placing several banners around the area to see if the effect is random or somehow localised but they all worked and showed up as one would expect.

1st picture: CK screen of the dungeon exit
2nd picture: Loaded game in dungeon and exited to see missing parts
3rd picture: re-entered dungeon and and exited to see that missing parts appeared.

Seems to be common bug with the CK. Large statics disappear after fast traveling to cell / switching between interior and exterior.
Only way to fix it I found was to double click the problematic pieces and turn on "is full LOD" in object properties, confirm it and then turn it off again. (keeping it on could cause performance issues on slower machines)

Thanks, that solution solved my statitcs running away.

I think i found one more way to fix the disappearing statics problem, continuing Maddox911 advice please uncheck the respawn in the object properties and confirm.
