Metacraft amulet beasts

I seemingly lost my 20 div base amulet while trying to add a metamod in menagerie, mobs didn't spawn and the amulet isn't anywhere to be found.
Sorry for my language in advance, but where the fuck did it go? Just hit a 0.7% All attribute roll on that badboy and would really like to get it back.
Cheers, keep it up team, appreciate your work.

P.S. Before menagerie I missclicked on the aspirants plaza wp, not sure if it means anything.
