[Ultra-Lite] Melee vs Ranged

In Ultra-Lite, I had one character with a good ranged attack and one with a good melee attack. In the Ultra-Lite combat, they just chose "move" all the time, one wanted to run to melee and one wanted to run to ranged. What's supposed to happen here? That they run into some wall or cliff?
