Problem with Turrets

I'm working on porting the turret resource to the preview SDK and ran into this problem.

I'm using the default vehicle instead of the player and a port of this resource..

When running the debug engine I immediately get an assertion when adding an AITurret to a map near the vehicle.
AssertFatal( !mSearchInProgress, "SceneContainer::castRayBase - Container queries are not re-entrant" );

The stack trace is

As far as I can tell this happens because findobjects() is called by the vehicle class to see it collided with a trigger, when it does then the AITurret code checks to see if the vehicle is in the line of sight, that second container search call causes the assertion:

The TGE container searches didn't seem to have reentrant check.
I'm not sure if I'm doing something wrong or this is a new restriction. It seems to be the latter so I'm not sure how to get this to work as originally intended.
For now I'll disable the LOS check.
thanks
