AT, the MG symbol file "MachineGunSymbol.png" is missing in SFTypesSymbols_Axis and SFTypesSymbol_Axis_West Facing.
You've included MachineGunGermanSymbol.png in those dirs but it's not always used in the scens, so both must be changed.
I'll do so next version, actually I'm working on forest terrain.
