I am having a problem in which Plantera is always spawning enraged. It has the aggressive behavior of charging at me, and is moving much faster and hitting harder than she is supposed to under normal conditions (at least in the videos I have watched). I am in the Underground Jungle, about two-thirds of the way down one of my two hellevators. I tested if she was enraged by moving to the surface, and she did not increase in speed or damage, so she had already been enraged. I have made several rounds of my arena to ensure it is all jungle, and the closest biomes to my arena are the crimson, which is on the other side of the temple in the jungle, and Hell, which is about the same distance away as the Crimson. The surface of the Jungle is twice the distance away as these two. I can't figure out why she becomes enraged, and I can't beat her like this, even with full Chlorophyte armor. I've tried various weapons such as the Light Discs, Flamethrower, Mega Shark (Chlorophyte bullets), Shotguns, Rainbow Wand, Magic Dagger, Beam Sword, the Chlorophyte sword, and a lot of other weapons (though the ones stated are probably my more powerful ones).
Is there a reason other than the ones I've checked that she should be enraged? Or is it a glitch? I made a thread about this and someone recommended I post this here too. I've been enjoying this game for a while, but this is extremely frustrating.
