Sporothrix and Arum Spinosa blueprints?

[RS219]

Does anyone know where to find these blasted things? They don't even seem to be listed as an iso-vault bounty drop with their respective parts.

I'm guessing they drop from that bile pit that Reb showed on stream.

I jumped down that pit yesterday after figuring out how to kill it. There wasn't anything special in it other than a fallen mech.

The new weapon parts are farmable from the T2 and T3 Arcana Vaults. As for the BPs, I have no idea where they are lol, no luck finding them.

The Wiki says that the BPs are farmed from the same source as their parts though, but it seems bugged right now.

I know about where the parts drop, I have 3 Sporothrix barrels and a receiver and just need the stock, then I can move on to Arum Spinosa. It's the blueprints I'm (and everyone else from the sounds of it) just clueless about.
