ive been trying to figure that out today
because from my PoV
my action shud work first, which shud then disable melkor's busdrive FROM his end, not my end. so abilities on me still go to melkor, but abilities on melkor shud not come to me
since pot's rabbit went from melkor to me, it's clear my ability failed PRIOR to pot's rabbit
someone else targeted me directly with an ability that stopped my ability, and it had more processing order than melkor's busdrive
its the only logical explaination from my PoV
