Yamato (U11) is a semi-incompatible with Slicing Dismemberment and Any Weapon Any Slot. Slicing Dismemberment causes more than just the shoulders, knees, and head to be cut with the anime slice and the game can't handle it. Any Weapon Any Slot makes sheathing the weapon impossible with the sheath.

The U11 update includes some changes to the way the game works, and the way that the user interface looks. This update was made in order to fix some of the issues that were present in the game, and to make it easier to use. The most important change is the way that the user interface looks.
