bullet types effects changed-strange results!

[Hellbender]

Yesterday, my Spitfire Ia_oct started burning after having been hit by a 109 with cannon and MG rounds. There was definite fire just behind the cockpit and a long trail of smoke behind my plane near Falkstone. However, I can´t tell whether it were the MG or the Cannon rounds making me burning like a candle. Took a pretty heavy burst into my fuselage, so I had to jump from the flamming wreckage.
