Unable to create polygon from board outline

[projectHFRGQ]

Hello,

I'm trying to create polygon from board outline but there's no "convert to polygon" option after right click (I guess after some updates) and "Polygon Pour from Outline" makes nothing. Should I do something else before making polygon pour from outline command?

Edit: I've found out that I'm unable to make this polygon only when the PCB is a circle.

This is a current limitation of the convert to polygon option. We recommend to use 2 half arc's for the board outline to work around this issue.
