Hey guys, 

Just wondering if anyone has bumped into this issue. I have 3 champs that I have made summoners. Right now I have full summon armies with them but one of them will not cast Air summon. He can only use it in battle. 

I have more than enough mana to maintain. But I can only call it up in battle - not on the world map and keep him like other summons. I have reloaded back to old saves and tried different summons. They all work it is simply the air summon. I shows in the bottom corner that he can indeed someone it but when I cast the spell outside of battle i get nothing. No icon to pick which hero will summon it - nothing. 

So is this a bug or am I missing something?
