Voronoi Tesselation Error

[skygering]

When I was running the Nares Strait simulation at timestep 20,000, I encountered this error. This is in the VoronoiCells package. I have been thinking of switching over to DelaunayTriangulation.jl for a while, but I think this has convinced me.

nested task error: KeyError: key -1 not found
