H15 Pyro Now Broken

I need to re-use a pyro scene I had created about a year ago as part of a project; here's a test render I had done on 5/19/16:

https://www.dropbox.com/s/y9tih2vxd2w2pce/PaperBurn_02.mp4?dl=0

I found an old autosave from that day (and the surrounding days), and when opened in either H15.5.863 or H16 .0.633 I get a test render looking like this:

https://www.dropbox.com/s/68dw58zxa6pno8m/PaperBurn_02_today.mp4?dl=0

For some reason, the temperature and heat fields completely balloon out within 20 fames & fill the entire grid. It's the same exact scene file from that day, but with completely different behavior - and I can't figure out why.

The shader feels out of whack too, as it looks incredibly overexposed. 

The only thing that comes to mind is if there was a change to the pyro solver in H15.5/H16 that needs to be accounted for.

Thoughts? I can strip the scene file of client content if need be. 

Thanks,

Luke

It's because you are working in houdini16. Things change from version to version. Sometimes things are added, split up or removed completely in the new version. Inoperable this helps. Try to check the node network and see if it has removed anything from your 2015 version.
