Hi,
I (and other user) have the problem, that sometimes a MP-aircraft after
resetting by its pilot is displayed at the last position before the
reset for a long while. In this cases, the time stamps of the packets
sent by the MP-aircraft have a much older timestamp than the last one
before the reset. Therefore they are all discarded, as long the time
stamp is not large enough. The attached patch fixes this. But I am not
sure, if the mMotionInfo.clear(); is all what is needed to do or if the
members need to be deleted (but probably not, the discarded packages are
now not deleted, too).
Please have o look on this and commit, if ok (without the debug cout).
