4.12.2 de-bugging

[stugumby]

I made a mission titled boston tea party, in it the a20c attack ijn ships and now in 412 when the a20 descend to torpedo height when they turn in on their run they simply ditch or wing over. Attack waypoint height was set at 500m to allow ai to manuever. skip bombing planes remained ok, it may be related to the attk waypoint but it is synchronized as much as possible with the ships position at the time of attack, ship has waypoints not just 1 at each end.
