I read the release notes and I didn't see any mention of fires occurring in a different set of criteria now.  I landed my Ta152H on the first night of the patch without a gear and after my wing ripped off (I prefer to land with just my fuselage  

), my plane caught on fire.  Out of the hundreds of gear less crash landings I have made in the Ta152, I have 
never seen it catch fire before and thought this was too huge of a coincidence. 
In addition to that, while I'm not 100%, witnessed what seemed to be a Spitfire ripping his wing off in a high speed, high G turn in which he then caught on fire.
Since I had never seen either of these things happen before in god knows how many hours I have played, I ask if the new patch code caused this or I have to chalk this up to bizarre astronomical alignments?
