When I open a new sculpt scene it works perfectly, but as I was editing my own model I must have pressed something by mistake and now it's disappeared. The green arrows are pointing to the diamater/radius/sculpt circle thingy that I'm talking about.
Also, if anyone knows the official name of that pinkish colored circle that would be very helpful, I might be able to simply find it in the UI myself if I knew what it was named... I'm calling it brush circle which is not an accurate description. :)
