Assorted Grim Feast and Wolf Pack bugs

Grim Feast is horribly broken right now.

Passively:
- Some of its remnants visually remain on the ground forever even after being picked up
- The buff provided by having Grim Feast on, which I can only assume is there to help us determine what percentage of its capacity we have currently stored, is subject only to the whims of Chaos itself; it randomly either stays at 0 despite having collected remnants, stays at some arbitrary number or only sometimes seem to increase, doesn't always decrease after having been used, and so forth.
- Remnant support gems don't seem to work with this skill. If they do, it's impossible to tell due to point 2
- Various other effects like passive skill tree nodes referring to remnants don't seem to work with this skill. If they do, it's impossible to tell due to point 2

Actively:
-The resurrection cannot be used despite allegedly having some capacity stored; player character visibly used the skill but nothing happens
-In case of Wolf Pack or Bind Spectre minions, their bodies disappear so quickly that there's only about half a second to 1 second window where resurrection can be used successfully. Once their bodies are visibly gone these minions cannot be resurrected by Grim Feast's active ability until they have reformed and died again. At which point again the player only has a very limited window to do so.
-Above bug possibly also happens with regular resurrecting skellies, however I was not able to determine whether it was part of that, or the aforementioned remnants not counting/pretending to be collected.

Notably Wolf Pack minion bodies disappearing so quickly also prevents making use of Unearth to generate bone constructs, which is not a bug but it leads me to question why do Wolf Pack and Spectre bodies disappear so quickly in the first place.
