SSE Placed fire rune spawns in a different interior cell in game.

[Grummulthrus]

Has anyone encountered this problem before?

 

I'm working on a mod with multiple interior cells. Let's call the two relevant cells $InteriorFoo and $InteriorBar.

 

The procedure:

 

1. In Creation Kit, I load $InteriorFoo and place a TrapRuneFireProjectile -- I'll call it MyTrapRef -- at coordinates $xyz.
2. I generate a new SEQ file, start Skyrim, and load a clean save.
3. MyTrapRef triggers in-game in cell $InteriorBar at coordinates $abc != $xyz.

• It is, reliably, in the same (new, wrong) position, in the same (new, wrong) cell.

 

This is hilarious, but also totally annoying. I do not want a fire trap on the tavern interior stairway.

 

Any hints on what's causing this?
