Hey dark_omni,
When you say log out, what do you mean by that? Are you just force closing? Are you backing out of the back and removing your account from Google Plays?
For issue 2, this is related to the Story mode version of the bug, so that fix will most likely fix the quest mode issue (I will check to confirm this). You saw that you still got experience, because of the experience you gained while your character was still alive, though they shouldn't get the scenario completion exp.
Thanks a bunch!
