So the rule for overlapping at the end of movement is to move a ship back until the bases are not overlapping any more. The ships are then "touching".
The rules then say that actions can't be performed by a ship that is overlapping another ship. This seems strange since by the time you are going to execute actions, your ships will never be overlapping.
I'm trying to determine whether this was a misuse of the word overlapping in the rule book (should have said "touching"?), or if I'm rather misunderstanding something.
