Well that's weird... (minor chapter 3 spoilers), Really broken glitch... Options

[Another Necromancer]

Okay, I was just wondering if this happened to anyone else. During the first assault on Platina battlefield, I defeat Eudy using the Mind Change card, and green lines of text appear below the morale damage calculations. As of the next battlefield, the first number (i.e. thousands column) of the power for Mind Change AND Revolution is corrupted-looking. I don't end up using the cards until the start of chapter four (Killed Gulcasa in two turns w/ Ace Guard, when normally I'd use those cards for their higher power) but when I do, their power leaps up to 9999. Yes, 9999.

I've already restarted because I don't like playing with a broken, glitchy advantage, but I was wondering if this has happened before or if my game needs to be quarantined and gassed.

It happens. Unknown how, but it's always Mind Change and Revolution.
If you still have the save, check Earthquake; it should be around 850 POW.
