Hi Jordan,
Sorry that I didn’t respond sooner, this topic seems to have slipped past my attention. 
The error you were initially seeing is related to some precision issues in our code for evaluating bezier curves. Changing the interpolation/knot type to corner will definitely solve that problem. The second error you are seeing is because your settings on the PRT FumeFX object suggests it should see particles in smoke (and/or Fire) but the FumeFX sim didn’t have that channel. Sounds like an error to me.
