Thanks for the correction! Although rare, ⿱艹妖 does exist, and I will submit new evidences. The character 妖 is a clerical-script abbreviation of 𡝩, yet in the modern writing system, 妖 has become the standard form, while 𡝩 has faded into obscurity. This unfamiliarity with 𡝩 may explain why it is occasionally written as ⿱艹妖.
