I am really enjoying the Blender program, but I am also having some extreme issues with it as well. It seems to "glitch out" randomly, and when I try to replicate the scenario, sometimes it will do it again, other times it will work correctly, and other times, it messes up completely differently! For instance, in the file that I attached, I am trying to create a "Firebending" effect. I have the smoke flow and domain set up, but for some reason, Blender keeps randomly duplicating the domain at different points throughout the video. I'm really not sure how else to describe it and get help because the events are so random and so confusing to me. I often follow video tutorials exactly, but if I mess up and have to undo a step, Blender loses its mind it seems. Is anyone willing to try and help me out with some of these problems? Thanks in advance!
PS: The video tutorial I am using is this fire power video if it helps you guys out with answering my question.
