ubernostrum regenerates two body parts when one is a missing tongue from glotrot

[Ethan Davidson]

Character had glotrot and lost their tongue, also got arm chewed off by madpole. After curing glotrot, taking ubernostrum caused both the tongue and the arm to regrow. Ubernostrum description says you regrow up to one severed appendage, so this kinda feels like a bug, but maybe the tongue doesn’t count as an appendage?
