When upresing simulation it all works fine up until some point, I can follow OpenGl density channel, it looks good, there is more resolution in it, which is nice but then the smoke gets completely wiped out in 5-6 frames. The upres simulation continues until the end but all of the voxels are completely empty where in base simulation there is still a lot of data present.
You are going to need to send Jascha a scene file and your TFD log
