It's just stop working from time to time without any pattern. Waiting for a bug fix is useless as I understood from Altium's plans. Is there any workaround for the issue?
It's not a matter of polygon ordering. Bringing on front or sending on back or rebuild/repour will not help. At some point Circuit Studio just stop pouring any new polygon regardless of net connection, polygon's location, etc... Slid regions seems work, but they don't have thermal relief feature and other useful settings as polygon does.
