Ok, cool, thanks for the reply. Hopefully TDW and Trevally will see this page and offer up some advice too, as it sounds like it'll need the input from all three (your equip dates, TDWs sub files and Trevally's OHII dates) in order for upgrades to work over consecutive campaigns. Maybe a new thread would be in order so the three of you have somewhere to interact without derailing existing threads.
