At the moment I use the skill, a hit mark has appeared then a stack consumed by nothing. I did nothing at all, but the hit mark appeared and the stacks consumed one by one periodically.(about once every five seconds)
I encountered this situation for the first time in cavia mission, then I confirmed this in simulacrum.
This bug was amended for less than 2 weeks and now its back with the Hotfix 35.5.7. Please amend. Justice for Qorvex
