there is probably a (minor) bug in V2:
see this simple test-board (connection between J1 and J2 not drawn for illustration):
creating a ground plane with thermal relief leads to this (no plane created at all):
a manual overwriting of the thermal spoke size (even the same size as predefined, here 0,3 mm) does the trick:
It seems to me that the predefined “0,3mm” are not taken into account and assumed =0.
