Had it happen on a few characters now where I pick up the candle on last boss, but then am unable to put it down. Can’t click off the debuff, and the extra button to drop it doesn’t appear on the screen.
Fight can still be handled as someone with the small candle buff can still refresh the duration of the large candle, but i’m just stuck holding and running around with the candle until the fight comes to an end.
This just happened to me as well. Tanked my entire run of a +13.
The extra action button to drop the candle never appears, and you can’t manually cancel the buff because it’s unfriendly. You also can’t take any actions while holding it, so it was an instant loss.
Are you not able to use a keybind for the extra action button to work around this? Haven’t personally experienced the issue so not sure if it would still work.
I’m not sure - i didn’t have time to look up the macro before we wiped, as it was a 13. But I’ll try next time. Even a /reload was too slow to live through. So aggravating 
Keybind the button, when this bug occurs (which can happen with any Extra Action Button ability), the keybind almost always still works!
I mean, it should be fixed, but this will save you from bricking keys when it does. (also realistically, this bug has existed for a very long time so I am not sure I see it getting fixed any time soon)
No need to make a macro; you can keybind it right in the standard settings (or in any bar mod you use if you happen to use one)
I did notice the first week on Gallywix that sometimes the extra action button for picking up a bomb wouldn’t appear for me, but the keybind did still work. So, that checks out to a degree.
Personally, I’ve never had the keybind fail when encountering this bug, and the first time I experienced it was on Ultraxion back in Dragonsoul! I just didn’t want to be speak in absolutes because it’s possible there are some scenarios where it doesn’t.
Keybinding that button is a good idea for speed anyway, but invaluable in the situations where you need to hit it but it doesn’t reliably appear.
