Error using well-package during "Gathering points on fractures"

[kralovcova]

Hello,
using well package, sometimes an error occurs during "Gathering points on fractures".

I run the "well example" model. The original model generates 400 fractures. I also tried to increase the fracture density .
The problem arises at a higher fracture density. If I increase nPoly to 1000, then processing the well data ends with an error: "IndexError: index 4 is out of bounds for axis 0 with size 4":
