That would be easiest - send the replay to somewhere EA only can see - and give the player a 4 digit code. Come on here and reference the code - voila.
Actually - should be able to do it for anything - I've had my MG's getting stuck - wont move, wont shoot - but it's so rare. It'd be nice to kind of click 'report' with the video and then once you come on here you can reference the code and the reason for report. EA can just ignore everything but what people actually report on here.
As for above - I've been up 5 units on people before - and it wasn't just 10 tib units - no 1337 hacking either. It's amazing the shock and awe you can do on an opponent doing a double harvester - LOL.
