This happens mostly when the fighters are quite a bit out of range of each other. Then the AI Peacock will just use "The Hole Idea" (her Character Ability where she disappears into the ground) again and again and again. This is very hard to do anything about as a player as the moment you stop blocking, she will use the offensive part of her CA. So either you are stuck blocking, while the AI wastes time doing this again and again, or you try to bait the AI by unblocking for a just a moment to try and get her to attack. This however is really risky, as you if you're too slow, the AI will be able to hit and combo you. If you are TOO QUICK however, the AI will not react and return to their loop of spamming the hole idea. This is quite frustrating to deal with, as the the AI becomes very unpredictable.
