Hi Antigame-Team, It appears that the Range of the sensorphalanx is not correct if it overhangs the system 1 or system 499. For example: Planet on position 1:1:7 with phalanx on level 5 (Range of 24 System in both directions) In this case Antigame indicates that the Range is from System 1:1 to 1:31. This is correct in non-donut-universes.
