Full synchronization challenge

[Bars]

Well guys, just so you know.
I just lost 10hrs of gameplay by falling through the map...

Yup, falling through the map.
I was flying with the eagle and scouting for places, all of the sudden I go out of the eagle and I just see Basim falling through the map and dying.

So in other words, when you're flying the eagle, do not ever be on a horse with autopathing on while doing it if you're playing full synch challenge.
