Cosmos I haven't seen before.

Hello. I was farming Cosmos at the sanctuary expedition event. Got a "Cosmo selection chest", and this Cosmo was there

(picture shows a Cosmo selection chest, has three Cosmo. From right to left are Silver Dragon, black widow and an unnamed, unknown cosmos, the art is a Handsome dude watching flowers of something)

I picked that Cosmo because I wanted to know what it was, but sadly it wasn't in my inventory. It wasn't in the codex, either.

I don't know if post it in the "bug" forum.
