Well if you are using the GW 24h mod, you need to install the basic.cfg fix so that things will work.
I have a seperate installation, where I have GW with Kid Mod and I didn't install the basic.cfg fix as there is no fatique.
In campain, everything works fine, but in SP mission, it get a type IIA conning tower
(gotta post the pic sometime) and lot of things are destroyed. In the normal GW, I have no problems!
