2x unit size for all
Disembark bug persist.
All naval units have 2 ships.
If you have the 160 men starting campaigns, and everything is correct, I would recommend ESF and setting the unit count to 3. Like described in this link: http://www.twcenter.net/forums/showthread.php?620839-How-to-edit-unit-sizes-in-Rome-II-total-war-(number-of-men-per-unit)
