Builtin content Missing

The following has been in all previous builds but is now showing missing in my Route
Built in Content - shows unknown location -- author Auran

<kuid:661281:85214> PBR Gravel 8 with Dirt - Seasonal

It is also missing from the 1950s Glory Years route by Robert3a0, and it is an Auran asset. No response from N3V? Maybe we should post in the General Forum....

EDIT: The sessions are missing more Auran assets. Where is N3V hiding the Auran assets?:
<kuid2:401543:1166:15>
<kuid:-25:1321>
<kuid2:401543:1161:5>

I have the latest update 109641 and all those assets show as built-in in CM.

Ah. Hopefully they will reappear if I install the new SP2 beta. I am on 105100 Platinum.
