Parts can become errorred after a server restart.

Can also happen when re-validating networks (such as placing a cable)

(Randomly try to re-enable inactive parts to improperly catch such bugs for now)

Variables don't reference other variables.

activeAspect in PartStateWriteBase can become null for some reason.
Can ONLY happen in in PartTypeWriteBase#updateActivation, so when a network element is deactivated (activeAspect set to null), but later again not activated again.
The cause of this might be clashing network elements because of a wrong compareTo implementation.

SMP-only?

Received no new reports up until now for the latest version 0.8.7.
