Array index is out of range

[MysticMTL]

I get this message box when starting out a new town, and clicking on the zoning icon to start building. I press "OK" and the message goes away,
and I can continue building. I'm just wondering if this is a serious error, and if it's alright that I ignore it?

Array index is out of range
[System.IndexOutOfRangeException]
Details: No details
System.IndexOutOfRangeException: Array index is out of range.
  at NetTool.SimulationStep () [0x00000] in <filename unknown>:0 
  at ToolManager.SimulationStepImpl (Int32 subStep) [0x00000] in <filename unknown>:0 |

Here are my system specs. Let me know if I need to provide any more details:

Hi MysticMTL! Have you encountered any more problems since you found this, or has it gone well playing after you got that error message? And do you happen to have the whole output_log available for this issue?
