In my current game, Resoln just decided to wardec me, and I see it has a stack of 13 armies on one square. I hit it with a Falling Star (wiping out 10 of them!), and am greeted with a series of messages telling me my Sovereign (by name, with her avatar image) teleported out safely and it cost x mana to do so, and she went to a specific city (all 3 notifications said the same place). Two small problems with that: 1) My Sovereign wasn't in range of that spell; she was, in fact, already immobilized in a city - the same one she supposedly teleported out to 3 times. 2) The game actually deducted the mana cost for the ENEMY champions and sovereign to port out from MY mana pool (I started the turn with over 400 mana, am now at 32 mana, spell only costs 150 - do the math).
Oh yeah, last point? My Sov had less than 5 turns to go to be mobile again. She's back at 5 now.
