nullRefException in ZoneBlock.SimulationStep

[SamsamTS]

Could prop be null in ZoneBlockDetour at Line 754?

foreach (var prop in buildingInfo.m_props)

It's the only thing I can see that would throw a NullReferenceException in SimulationStep.

Yes, maybe m_props is null in some cases.

What I had in mind is that if prop is null then it would throw an exception when you try to access m_position on the next line :

biggestPropPosZ = Mathf.Max(biggestPropPosZ, buildingInfo.m_expandFrontYard ? prop.m_position.z : -prop.m_position.z);

so maybe you should add a test, it wouldn't hurt.

if (prop != null) biggestPropPosZ = Mathf.Max(biggestPropPosZ, buildingInfo.m_expandFrontYard ? prop.m_position.z : -prop.m_position.z);

EDIT: But I guess if m_prop is null it would also throw a NullReferenceException

I pushed a fix to master. Do you know how to enable line numbers in exceptions? That would be so helpful.

[SamsamTS]

The game isn't compiled in debug mode so no line numbers unfortunately. Maybe with a hacked mono VM or something.

Nailed it down. This is the issue:
