Yes, I'm so sorry, it's been like that for a while now. I had to disable it, because I noticed that my logic was idiotic, but haven't replaced it, yet. Drove me crazy, though

, because I forgot about it and it was ACTUALLY, really the brush, virtually painting into the gui before you would paint onto the canvas, triggering the random generator and offsetting other parameters and all that nonsense, hehe

. In the very beginning it wasn't a problem, but then, when the brushes became more sophisticated, it started causing troubles.
SO, yes, it WILL come back, but currently it's off. however, I put a little "needle" in there, so you can see where the BIAS is at.
