Invalid initial tile direction during placement

[sim642]

JCloisterZone correctly shows the positions where a new tile can be placed, but occasionally hovering over one of them shows the tile in an invalid direction. If all the possible positions are already identified, then they must account for all the rotations of the tile being placed, so it could be immediately shown in a valid direction.

When rotating the tile in such place, it goes to a valid direction and right clicking only cycles through valid rotations.
