I hope they are going to fix the problem of aircraft dissapearing on landing that are done in a mission using the new taxi routine, this was such a superb addition to the sim that has the immersion aspect spoiled when your own aircraft as AI stops on the runway and every other aircraft in the circuit vanishes as they land.
Bitching apart this has to be one of the finest patches these guys have done, can't imagine what they could do next that would better 4.12.
Wishing you all the very best, Pete.
