Since installing 9.0.4, it’s suddenly throwing errors about overlapping copper zones with the same priority. “Intersecting zones must have distinct priorities”. The trouble is, they’re the same net, so why would that be a problem? They’re going to fill fully either way.
Is there a workaround? A board I designed in an older version has quite a few of these and I’d rather not change priority all over the place, as it could lead to another error.
