Using Gems in Combat and Holding Positions

[Mysterio]

Hey, folks. I have a couple things I'm seeing during battles and wonder if you guys can explain why they're happening:

1. I have a mage who's level 3 in a path who's been ordered to cast a level 4 global battlefield spell in that same path. He has 10 gems of the associated path in his inventory, yet didn't cast the spell in battle. Since he's level 3, he can use 3 gems max to cast the spell. It's a 100 fatigue spell, so one gem is used to boost his level to 4 for the single casting and two more can be used to reduce fatigue. So, why did he cast Personal Luck instead of the level 4 spell?

When he was recruited, he was level 1 in the path. I used empowerment to get him to level 3. Could it be the game thinks he's still at level 1? If so, then that's a major bug. Does anyone have a theory? If not, I'll be submitting this as a bug report.

2. I give my level 1 priests the following order: (Banishment)(Banishment)(Banishment)(Banishment)(B anishment)Spells. Even though I have them aligned in a line from top to bottom, they all gather into a clump in the bottom left corner of the battlefield. My theory is that if they don't have a valid target for Banishment, they cast Bless on the first round if there's a valid target, but then do a "stay behind troops" when they don't have one for banishment instead of staying put. Has anyone else seen this behavior? I want them to maintain the line, not clump together in the corner.

Thanks!
