I wanted to try out painting on mesh maps to fix baking errors. I've never really done this before. In the first image you can see there is a bit of pinching on my normal map so I exported it and edited it in photoshop. In the second image you can see that I was able to fix the pinching but now I have these weird stripes on the normal map.

Why is this happening? Did I mess up some export setting in photoshop? Is there some better way of painting out bake errors? I'm also trying to tweak a curvature map in Photoshop and the export ends up being a different brightness than the original for some reason which makes it unusable. Not sure what I'm doing wrong. I've heard other people say that they edit their mesh maps in photoshop.

Edit: After posting I see that the image quality has been downgraded so its hard to see the stripes I'm talking about but I can assure you that they are very visible and ugly.

Edit 2: I've solved the problem. I found that the stripes don't show up if I use the "Save a copy" option instead of the "Export as" in photoshop. I'm guessing this is due to some compression that the "Export as" does. I've been using photoshop for so many years and had no idea that there was any meaningful difference between these two options and that apparently "Save a copy" is more lossless than "export as". You learn something new everyday I guess. Thanks to anyone who took a second to look at this.

(Skip to the end of the video to see her attack my hand. I opted to not cut down the video so you can analyze her body language and see she is seemingly enjoying being pet for quite a while. The video is muted because its just me breathing lol but I am absolutely certain no sudden loud noises happened to cause her to react.)

I was petting my cat and happened to be videoing her because I thought it was cute when she suddenly attacked my hand. She has never done this before. Its actually something of a miracle I happened to be filming and caught it on video. What caused this? How can I avoid this from happening again?

She is a very chill cat overall. The only times she gets upset and bites when being pet is only if you touch her in some place she doesn't like (her paws, her tail) She has never reacted negatively from petting her head/neck like this. But usually when she is done being pet she will try to walk away and/or start meowing for me to stop. I've never seen her do a surprise attack like this. I thought she was enjoying being pet here. I'm left very confused. Did I do something wrong?

TLDR: my cat bit me while petting her, I have no idea why.
