Before you send in Night actions, one more thing I would like to point out.
You know it's forbidden to miss-use Battle/Day Actions that you can't perform, this was a rule before but wasn't much highlighted. This is now emphasized due to the fact each day you have refreshed ##SHOOT action.
If you can't SHOOT, don't try to prove it next Day (e.g. "look I can't shoot because I typed but GM ignored it, so I must be a building/submerged/something else"). For this reason there will be a penalty in place, and most likely if someone miss-uses SHOOT (or any other) action, their first coordinates will be revealed on naval map (the first unit tile from top left).
Thanks for understanding, this is just a precaution so that the game mechanics won't be abused as much.
