Hello and thanks for the report!
This is momentary, correct? I can repro it but only for a second at a time. It is pretty awesome and the animation with the fire sword is certainly something to behold.
I'll make a note on our bug tracker for this one, but it's probably not going to be fixed for a while. The reason it happens is due to a middle ground we reached with that mechanic while testing. As far as I can remember, a moment had to be picked where that animation would cut off while jetpacking, and that momentary 90 degree turn is about as good as it gets without a deep dive.
Thanks once again for the report and thanks for playing Clone Drone in the Danger Zone! :-)
