Bug report: When you try to place an entity on the board that has a width of less than five (the largest piece), the smaller piece shows up at an offset from where you actually try to place it.

Example: Place a sub (three chars wide) at A7r. You can't. You must place it at A5r, in which case it appears at A6r, extends right three places, and leaves a blank slot in A10.

It also seems (in the one game I played) that the computer placed two pieces overlapping. I could be wrong on that though.
