Thanks shiggy and witch; this explains the errors I've been getting with Awesome story progression on.
The only mods I use in the game is Awesome and NRAAS ErrorTrap.

Basically
    <sim> failed executing FindHome
    <sim> failed executing Split
This has been going on for at least a month, but I've been away from the game since summer.

I'm on patch 1.67.2.024001
It does not matter which world/game I play, as long as Awesome Story is running the errors happen all sim day long,

When NRAAS is turned on ErrorTrap running there seem to be more errors.  (attached one)

Keeping Awesome Story turned off, everything else seems to work ok, and EA story progression does its usual thing.
