Hi everyone, I hope you are doing well.
I’m currently have this issue when using Human to Sky Relation. Can someone please explain to me what is it and how can I fix it?
Thank you so much for your time!

@binh96123 it looks like you are using an older version, try updating with the pollination grasshopper installer and see if the issue persists.
