I've had this happen actually a few times in our games
I move a ship.
It's final position just touches my opponents ships, but doesn't overlap.
We always played it as a collision, so therefore he would lose his action and not able to fire at that ship.
I've been seeing some discussion on here so it makes me question as what we are doing wrong.
Since technically they didn't over lap.
Just touching.
Does the original ship still get his actions and can fire at the ship where his base is touching
