Masteria Expansions, Names and the proof for each

i just attempted to upgrade a stirge on a string to a stirge on a rope, and it gave me a stirge-o-whip o.O i skipped an upgrade! i guess if i can fail and it can downgrade it can double upgrade too

EDIT: i tried to upgrade my stirge-o-whip again, and guess what? it gave me a stirge on a string again T.T
