I haven't seen this question during a search.
I have a simple campfire simulation with smoke. When I play the animation through the first time, smoke and fire both appear and evolve correctly. HOWEVER, the next time I play it through, the smoke/fire retains the shape and color it had on the final frame. It's as though once the simulation is stopped, the fire is frozen in that form for all the previous frames. Is this a bug, or have I messed up somewhere?
My rig is: AMD FX-8310 8 core processor 8G RAM GeForce GTX 970 graphics card
It's being rendered in Cycles by CPU, but the problem shows up before rendering. Unfortunately, I haven't been able to try this on another computer, or on another version of Blender.
[EDITED TO ADD:] Sorry, I have no idea how to attach a file to this post. HOWEVER, I have uploaded my .blend to google drive.
