[Title] A cursory Ctrl-F of “hatch panel” in the rulebook found nothing prohibiting this; any second opinions?
You cant remove game pieces scored.
section 8 G5. page 48
“Don’t mess with opponents’ scored GAME PIECES. A ROBOT may not remove a GAME PIECE
from an opponents’ ROCKET/CARGO SHIP. GAME PIECES which become dislodged because of
incidental contact with the ROCKET/CARGO SHIP are not considered a violation of this rule”
