Carbon Target NullPointer

Carbon target sometimes seems to throw a null pointer exception. Simulation was run for 20 years.

Appears to be everywhere timeservice is used.

From that stack trace it appears the error is due to not being able to find the necessary carbon report.

Fixed, because BLAM!
