Windows 8.1 x64, nVidia 740M
Worked: None that I can remember (since v 2.72)
Short description of error
Simulation cache disappears without a reason
Exact steps for others to reproduce the error
Simply make a Quick Smoke simulation.
Then play a bit with the frames (move forward and backwards) - you already should have lost your cache.
Let's say you were lucky and you did NOT: Start rendering say 5 frames and stop.
Come one day after and try to start from frame #6... You simply can't.
