Getting an issue trying to use 5 tickets at once, initially kon's bonanza, but tried other missions and it fails as well. You click/tap the Start Quest button, it bounces up and down responding to feedback, but never actually starts the quest. This is on Nox emulator running 11.2 downloaded from this post. This used to happen in previous versions, but restarting the game and/or emulator would usually fix it. Restarting multiple times has had no affect this version. Note, unchecking the "use 5 soul tickets" and doing it a single ticket at a time works fine. Had this occur with 2 different accounts on 2 different emulator instances, both running android 7.
