Playing through Awakening the Machine on my Rogue. Cleared to Wave 20 and Vanished as the Awakened Phalanx spawned in a vain attempt to make Deathstalker’s Mark halfway functional and the Awakened Phalanx reset, but didn’t despawn, and now it’s non-interactive and the scenario is stuck.
Edit: Just redid the event, this time with a plan to absolutely vanish on Wave 20 with the Awakened Phalanx engaged and taking damage. Bugged again.
I had the same issue when using Vanish.
Not being able to use the fun new heroic talents due to Vanish breaking things is pretty rough.
same issue - repeatable bug
adding to this as well
4 rogues! I think that’s all of what’s left of our shambles of a class!
Having the same issue atm.
Same issue with Invisibility on my mage 
bugged when using feign death(hunter) as well
Half the time the game doesn’t drop combat and let you restealth between waves, and then we get rewarded for wasting a Vanish CD by being told we just wasted our time for 20 waves. That’s super cool!
I’m currently stuck in here as well. Vanished to get more Between the Eyes casts on the Awakened Phalanx and it reset, now it and Speaker Kuldas are just sitting there.
Nice to know a major source of damage is just unusable in solo content. very cool very exciting very blizzard
seconded on hunter Feign Death
Bugged with shadowmeld as well. Stuck in event.
Happened to me too. Vanished for more Between the Eyes and bugged the event, wasting 10-15 minutes (of basically waiting) to get to this point.
Bump, please fix
Same issue on my rogue, please fix this
still an issue
still happening. vanish also breaks the nullification bots – they’ll just keep channeling until the 3-minute cast ends. neither they nor the target of their cast can be damaged or cced until the channel ends. it doesn’t break the run but it’s not super fun sitting there doing nothing for several minutes. once the channel ends, they reset and can then be killed normally.
