Creating or Cloning an Egg results in on-fire egg animation

[ghramsey]

I tried creating a couple new eggs in the M18 second nest.
I removed an open egg and substituted an unopened one in it's place.
Used same parameters set on the two unopened eggs at the beginning.

I placed two eggs. One in the tunnel past the alien drop scene and another
in the last tunnel where we drop in to avoid the runaway trams.

All of that worked OK. Eggs agro, huggers spawn and are able to be killed.
No busted collision stuff now.

BUT as a side effect, the eggs are spawning in an on-fire state.
I made a YT video showing this: https://www.youtube.com/embed/pR-rFw1h0vo

There's no option on any of the open or closed eggs to set fire condition.
I wondered if maybe there's a zone overriding the condition globally.
The moved eggs are not in a triggersquence.

I tried moving one of the stock eggs. This egg spawns without fire.
And works normally.

So something seems to be wrong with cloning or creating new eggs.

I have not tried making an egg anywhere else.
This is actually my first attempt ever. So this might have been present for awhile.
