Coming Calamity Disapears

I had 2 of the coming calamity. last night one disapeared from my character, i thought that was strange, maybe i put it in my inventory. i have over 100 tabs to go through. nothing. nowhere to be found. i then equipped my second one. i put all the support gems in, went into a map, died instantly. look in my inventory, and no coming calamity equppewd. gone again. both of them have been deleted. that cost me over 400 divine, and they are both just gone.
