Spells: Wizard spells - Abscond/Evacuate incorrect mana costs

[Kaem]

I think you guys may be misunderstanding what I am saying the issue is. Maybe my title is misleading?

I know Abscond mana cost is 600. I know Evacuate is 300.

The issue is that the mana used when casting these spells is not correct. In some cases I have had it drain 1800 mana with one cast of Abscond. Or drain 1800 mana from each caster in a group when I cast Evacuate.
