Game crashes click on guild in friend tab.

I'm getting a random crash about once a day when I click on the guild tab to see members online. Also I crash a few times a day after alt tabbing back into the game and when I start the cast to proc burning ground it triggers it. I'm noticing extremely high cpu usage, I've noticed the same thing with every streamer. I guess I'm going back to disabling core 0 until the cpu overload is fixed again. Rip my 7800x3d... It's cooked af! Second one!
