If a player scores a hold point from a battlefield, then moves their last unit out (making it uncontrolled), then moves another unit into that same battlefield during the same turn, does a showdown occur and can they score again?

Ruling: The battlefield becomes uncontrolled when the last unit leaves. When a unit enters that battlefield, a showdown occurs because the player is attempting to gain control of a battlefield they don't control. However, the player does not score or conquer again because they already scored from that battlefield this turn.

Sequence:

• Player scores hold point from battlefield
• Player moves last unit out, battlefield becomes uncontrolled
• Player moves another unit into the battlefield
• Showdown occurs (non-combat)
• If player gains control, no additional scoring occurs

Nuances:

• The showdown is non-combat
• The restriction on scoring/conquering applies because the battlefield was already scored this turn
