Fairly early on in the fight (maybe about a half hour in?) I, for no particular reason, decided to have Penelo summon Zodiark. The way things worked out, Yiazmat used Cyclone and then immediately after that, the summon went through. Then, something went really weird. I couldn’t seem to do anything, so I dismissed Zodiark.
When Yiazmat was dismissed, Penelo was completely alone, Yiazmat nowhere in sight. Penelo seemed to be completely rooted to where she was, I couldn’t do anything. Not only that, but the graphics all around her were really glitchy and blocky and weird. I couldn’t figure out what to do. My other characters didn’t seem to be anywhere in range and weren’t accepting commands. And I think they had been poisoned or petrified or something. So anyway, I eventually decided to just kill off Penelo and then switched in some other party members. I don’t know how, but that worked. Yiazmat was back and there were ultimately no more weird glitches.
Has anyone else here ever experienced anything like this while playing FFXII?
That is my only idea since as I said I have NEVER even heard of this before.
BTW, when I said in my post above "I couldn’t do anything," that was a bit of an exaggeration. I could still access the battle menu and game menu. Obviously, otherwise I wouldn’t have been able to kill off Penelo or switch in other characters. What I couldn’t do is move anywhere (Penelo was completely glued to the spot, like something out of Rocky Horror Picture Show) or target / use commands for any other active character.
Also about the Penelo movement did you check to see if she was Immoblized? I know seems silly to ask but I have had someone before run into something similar in another game and it was simiply them not paying attention to their status. And a big fight like that espically since it drags on you might not notice it happening though it still doesn’t explain the graphic flaw you reportred.
