I am having most of the same problems the rest of you are listing here. Tried OMC pack last night and most of the same problems listed here happened to me in OMC, too.
The zoom-in turret freeze is debilitating, but like another poster here, I figured out how to get out of it, albeit dangerously - just start driving and in a few meters (I think about 75 meters for me, as I remember) your zoom will unfreeze and you can go back to arcade mode.
Either both OMC and Aslain missed something (which Aslain cannot check until Europe gets 9.7) or something is new in 9.7 that is confounding modders atm.
OMC is a great mod, but Aslain's is the greatest. Aslain's type is larger and easier to read than OMC's and Aslain has a 60X Zoom, OMC does not. Aslain's also supports his mod a bit better and with more personal service.
I am confident Aslain will fix this stuff and I thank him for doing all this work so I don't have to!
Keep it up, Aslain!
