Good catch, I think I might've seen that before. Might be a facet ordering issue if it's sporadic :thinking:

Observation: The facet issue does not crash Terasology, so it's possible to close the warning and try creating a world again. However, when attempting to do so, Terasology crashes due to a NullPointer when fetching a component from a prefab. In particular, the NameGenerator component is null although it's definitely included in the prefab, so any access attempts on it result in an NPE.

This issue was not yet observed without the preceding facet issue.

At this point in time it is unclear, what about the facet issue causes this behavior - likely something is not properly cleaned up if world generation fails at the stage that it does.
