The MH-60S, UH-1Y and MV-22B do not have an option in the garage to fold into stowed configuration, at least in the released build. This can make mission creation aboard the Freedom, Khe Sanh, and Nimitz more difficult due to the reduced space available on already cramped vessels. The CH-53, and AH-1 already offer this feature.
Also, the AH-1 Also lacks a dash in its Eden and Zeus names. It reads "AH1Z" when it should read "AH-1Z." This affects the USMC and AAF versions
EDIT: The UH-1Y appears to be affected by the rotor fold "bug" as well
