Thanks for your reply, its strange beacuse I tested with all japanese maps, and it seems that Okinawa the only one giving problems. (I'm using the Vp compability BTW).
I'm playing DCG with vp 1.2 on stocks campaign, and it seems to work fine on most of the campaigns, but Okinawa all planes explodes on start, or they start on air with engine off. Is this a Vp problem?
