weird embark behavior

[eskuche]

Setup: '41 axis turn 1
Palau base defense force (garrisoned) can embark but not invade anywhere, even though it has full op points. If you undo disembark on its home hex, it keeps two op points but can no longer move.

More testing, has to do with unit starting garrisoned. Garrisoned embarking units cannot invade, only disembark. That explains part of it, but not the weird undo bug.

[AlvaroSousa]

Garrison units can't invade that is correct.

Units in garrison status may not use landing craft.
