Desconnection and rollback

Still here!
I was 99% of the next level, used t16 waystone on the node with boss, killed first pack on the map, got levelup, opened passives screen and DC occurred after a few seconds.
And you know what? Exp is gone, i'm still 99% and ALSO t16 waystone is gone and map node is clear of bonuses! That's so frustrating! =(
