Aliasing cabochon_(artist) → bastion_(artist)
Link to alias

Reason:

https://e621.net/artist/show?name=bastion says "Cabochon is Bastion's old FurAffinity account."

I was skeptical (my default setting probably) at first, since neither FA userpage refer to the other FA account.

Comparing FA Cabochon and Bastion galleries:

( https://inkbunny.net/Bastion says artist FA is https://www.furaffinity.net/user/Bastion

Various artworks in both Bastion's FA and Bastion's Inkbunny.
Example: '[P] Kailestis' from five days ago : https://inkbunny.net/s/1966987 and https://www.furaffinity.net/view/32921800/ )

Suggesting artist tag of cabochon_(artist) because there is also gemstone type Cabochon (Wikipedia ).

Suggesting artist tag of bastion_(artist),
(and maybe alias bastion to bastion_(disambiguation)
because
at least 2 uploads tagged with plain bastion artist tag were not by artist Bastion. ( post #1986234 and post #1986226 , which depict a character named Bastion)
AND there are other Bastions: (e621 tags)
1) 7 . . . bastion_(character) . . . character
2) 6 . . . bastion_(game) . . . copyright
3) 7 . . . bastion_(mnty) . . . character
4) 1 . . . bastion_(olliver_cottontail) . . . character
5) 124 . . . bastion_(overwatch) . . . character
