Clone Stamp affecting opposite side of model? Relatively new to Blender! I have a textured model, and I'm trying to clean up some messy seams. (Long-term I should have placed my UV seams in less visible locations, but at this point, I'd rather use the clone stamp to fix things than repaint my entire model)

When I use the clone stamp, I set the source with the 3D cursor, but when I go to paint, the area I'm trying to paint is not affected, but instead, the opposite side is painted in unpredictable ways:




No clue why this is happening or how to fix it, the only modifier have applied is subsurf, and I can't find any mirroring options that could be affecting the clone tool. Any help is appreciated. (Using blender 2.8)
User Moonboots Had the (rather simple) answer, I had some flipped normals affecting where the clone tool was cloning!
