Fume Simulation issues

[Jordan]

i think you will find this is an issue with pflow and changing particle count. When one particle is deleted or gets moved to another even it changes the the order in which the mesh is built so fumeFX gets told that the mesh is flicking around a lot. EG. Particle 1 creates face 1, particle 2 creates face 2, Particle 3 creates face 3. If you delete particle 2, Particle 3 would now create face 2 so fumeFX would just think particle 3 had been removed and particle 2 moved to where particle 3 is. This created a lot of random velocities. Gotta love Pflow
The solution would be to make sure the particle count dosent change and there is only one event.
