I just took the time to do the Scavebger’s Chasm Jumping Puzzle in Malchor’s leap in the hopes of getting ascended mats from the three chests at the end. It was my understanding that JP chests always drop a few ascended mats (up until I did this puzzle I had gotten them 100% of the time from about 18 other puzzles and mini dungeons), but NONE of the three chests here dropped them. Seems to me like the chests drops did not get upgraded when the others did.
