I have screen captures - but having trouble making posts with images.

Summary of issue:
Under research spell tab in spell book - as the game progresses the cost of "Spell on Domination" decreases.

Currently the cost is listed as "1181" and when I click "research" it reports two turns to cast.

When I switch to the "Magic Panel" the research time is listed at 87 turns (Cost is 70,000?)

Clearly this is some kind of bug:
(1) Either it is not intended for the spell of domination to decrease over time OR
(2) The Magic Panel is mis-reporting the time to research
