Twice in a row the Steel Path version of the "Alchemy" Bounty for the Cavia had an issue with not being able to complete the secondary objective. In this case, it was "Kill 3 Flying Murmur" but they weren't spawning at all. In both cases, the Gruzzling was the only "Flying Murmer" that spawned and counted toward the bounty, but it only counted as one. We waited and ran around the map for way longer than the normal bounty should have taken, and not a single one spawned.
