The Promethium Spur exotic legs have a new bug where if you cast your rift manually then your rift energy becomes full again. The exotic will no longer activate on enemy kills which means that it will no longer place a rift at the target location. The only way to fix this in game is to not cast your rift at all which is obviously not very practical for gameplay, go to orbit or to switch to phoenix dive then back to rift which isn't possible to do in locked loadout activities. Obviously this is a massive issue since it renders the exotic almost completely useless since it won't spawn the rift as intended on weapon kills, please address this issue quickly since the spurs are one of my favorite exotics but this bug makes using them hard to justify.
