Disturbing SimObject random deletion

I am asking now incase someone has encountered this. I am running into cases where random objects are getting deleted. Sometimes it's a sound, sometimes it's an imagedatablock, sometimes it's a scriptobject!

The result is that sometimes the game crashes or can't continue depending on what's gone missing.

I have never encountered this behavior before in Torque at all, so I'm not sure where to begin looking.
