[BUG] then [CRASH] - Tactical Battle/Burning Hands(?)/Trolls

Had a bug during a tactical battle, and then after completion of the battle I had a crash.

What I'm a little foggy about:

- During the battle, which involved my Sovereign and three Champions fighting 5 trolls I thing (three normal, one shaman, and a giant I think), my recollection is that I was going to use my sovereign to cast burning hands then went look at the trolls resistances.

- After checking out the enemy descriptions by clicking on the icons on the left side of the screen, my sovereign could not do anything, no attack no spell.

What I am certain about:

- My sovereign could not either cast her spell or attack any of the trolls around her.

- A yellow info box would pop up as I moved the cursor around that would say "this tile is out of range" or something to that effect.

- Then all the characters (Sovereign, champions and trolls) disappeared, but their heatlth bars remained on screen.

- I selected the hourglass to end her turn and they all reappeared--the battle then finished normally with everyone being able to attack.

- Upon completion of the battle, after dismissing the battle summary screen, the game crashed.
