I currently have a companion riven that can't be equipped on any weapon except deconstructor. My last two, I used Vulcax, and had no issues. One of my clan members has/had one that he couldn't seem to get to work on anything. Not sure if he has all of the weapon types or not. Very frustrating when you have to go through the full arsenal to find a weapon type that can hold a riven that doesn't specifically say that it requires one.
So I watched the latest prime time, and got the twitch drop of the simaris glyph. I had no problem putting it on as my glyph, but something weird happens if you go to the load out UI; it shows as the tennocon glyph instead. Anyone else having this issue? http://imgur.com/a/QAORlYt
