Game Mechanics: Soulbound Keys Disappearing

[Not Sure]

happened to me about a month ago, there is a petition with all the specifics, but same scenario as Azzudnxx, died in sky, looted just sky key bag, took keys out, placed seb/hs key in bag, died again, and they were gone. Not sure if they disappeared before or after the rez, I failed to look at my inventory while waiting in WFP.
