Short description of error
particle emitting from first frame location of emitter and also the first few particles appear to freeze in mid air.blend, baking the simulation to keyframes returns the same result, so not related to:
Exact steps for others to reproduce the error
add a particle system (emitter) to a moving object and press play. Happens on both rigid body dynamic driven objects and also after baking the simulation to keyframes.
See file, the particles initially emitted float in mid air completely frozen, whilst more particles continue to emit from that same location. Particles also continue emitting from the moving emitter.
