Backstory:
I created a dungeon with a working guard/jail system. It is connected to the world.

When I get sent to jail for breaking a law A dragon spawns INDOORS. It flies around in the gray void.

There are no dragons in the interior cell.

How does this happen and how do I stop it?

Did you set tamrial as a parent cell, or somethig? Or perhaps use a keyword or set a location that might be used in the dragon spawn scripts? Seems odd.

My Exterior jail marker (that's linked to where you get teleported to prison) is indoors...but I figured it is more exterior as outside the jail cell than outside the cell. There doesn't 'seem' to be anything signifying tamrial.

this might happen if you are using Share sky cell with the parent location

dragons will enter airspace with any shared sky cells of its children

ugh, The dragon literally spawns only when I get sent to jail and the jail is in the same interior cell as the rest of the mod. Never seen a dragon there unless I got to jail.
