Fated LFR dropping low level mystic anima spherule

I did some fated LFR bosses tonight and get a weapon spherule drop but it dropped at 187 iLvl instead of the expected 265/272. I’m not sure if it was Denathrius or Huntsman but it was the only item that dropped at season 1 iLvl.

Did it by any chance get sent to your mail and you looted it from there?

Sounds very similar to this
