Mirage with Miter/Panthera severely degrades performance

[Sennera]

I know Mirage has created tons of problems since release, but this combo (Mirage + Miter or Panthera) had a far stronger impact on performance than any other weapon I've seen on a Mirage. In a mission I had a Mirage with one of those 2 weapons, imagine a hundred flying, bouncing, physical blades in one room and how much processing is needed to support that.

Not only did my computer chug trying to display this, but at the end of mission I got an almost entirely blank mission result screen aside from a couple incomplete datum paths, and in the liset it displayed the results of the mission prior to that one. I don't even know if I got mission rewards from that buggy mission as there's no way to check.
