I Incorporated everything in the gif so hopefully someone can see what is wrong, I am using default settings as well.. Had a completely fresh reinstall of blender and the one I used on my now dead HDD is blender 2.81. The only addons I have added were CATS and some atlasing tool for CATS, which is a program to help quicken the process to port certain models to VRChat, this is helpful in a lot of ways to quickly pose the model and such. As well as merge different armature. Shouldn't touch anything sculpting related.
I am... genuinely curious as to what is going on here. I'm just sculpting and some mesh/Vertices aren't getting dragged when they should be. I watched a video and they said to try and apply scale. I did that, didn't help much at all. I'm at a loss right now.
