I noticed something weird today, and saw it happen 3 or 4 times (3 or so times in patrol, and once in a strike) while playing top tree solar titan. I was unable to figure out what exactly was causing it to deliberately reproduce the effect to make your lives easier for troubleshooting unfortunately.
Rarely, Upon killing an enemy with a kinetic weapon (observed to happen with Spiteful Fang and a year one Osirus SMG) the enemy would explode with the same animation and effect as if struck with top tree super (Hammer of Sol)... and would cause all said enemy's friends to explode if nearby as well. I did not have any luck attempting to isolate cause/trigger, but in case it is relevant,I was playing on PC, I had Lord of Wolves equipped the entire time, and a Roar of the Bear rocket launcher equipped as well. I observed it happen twice I think it was in patrol on the moon, once in a lost sector on the moon, and once during a playlist strike. I don't think I saw it happen in gambit, but again, it was pretty rare and seemingly completely random.
From what I can see looking around, it does not appear to be a current known issue/bug/glitch. I may try looking into it more tomorrow and see if maybe i can get video of it happening, but for now all I am able to do is scratch my head trying to figure out what's going on with that. I'm beginning to wonder if I'm just crazy and imagining it... hence the desire to see if I can get it to happen again on video to assist figuring it out.
