The Echo of Remnants fragment says "your lingering grenade effects (Vortex Grenade, Void Wall, Void Spike, and Axion Bolt) have increased duration." But it seems an awful lot like Echo of Remnants doesn't actually have an effect on Axions because they just keep going anyways to the point that the tracking gets weaker and they just start bouncing off the ground repeatedly. Isn't that what the fragment is supposed to have them do? You might end up spawning one that does not track or move anywhere and it just sits there... for a really long time without being shot. This is not counting the fact that apparently charged Axion Bolts with Contraverse Hold have a larger radius to spawn them for enemies. Don't know if that one is a bug, but there's never been a patch note for that and they started doing that last season. Also Cataclysm Nova Bombs no longer detonate when being shot by the user. I don't know if this is a bug either because it doesn't say that you can do that in the game anymore. I don't recall seeing a patch note about that either.
