PMVcomfRecipe Error

Hey guys,

I get an error using the PMV comfort tool. I have used it several times in the same script but for this specific geometry it won't work. The Traceback is to a check of the terrain. Is there anyone that can help fix this?  

Thanks a lot

Error:

Runtime error (ValueErrorException): need more than 3 values to unpack
