What: Upon using the examine tool, the description gives the character height even if polymorphed and the disguise is not pierced. (Ex. Character Disguised as a Cat/Midnight Cat. "This character does not seem to be disguised." Immediately followed by "This character seems about five and one half feet tall.") This seems to somewhat reveal a disguise even if it claims they are not disguised.
Where: Map unimportant. Noticed in Mist Camp.
Recreate: Use the Examine tool on a Polymorph Disguise with no Spot.
