Grim Feast remnants not supported by gems or tree

After calculating the % gain vs the life of a minion death, it is clear that remnants spawned by grim feast only stores the base life % of the gem (35%).

Remnant effect from tree does not work.
Remnant effect from remnant potency does not work
Delayed remnant effect from remnant potency III does not work
Extra remnants from Harmonic remnants and tree does not work

Twice effect from Empowering remnants node works!


Please fix :)
