Just tried leveling a Chinchou to Lanturn and its skill list is all over the place.
At lv 29, the system prompt me to learn Signal Beam, but in reality it was Swallow
At lv 33, it shows as Flail, but in reality it was Stockpile
At lv 37, learning screen show Discharge while it actually was Signal Beam.
I haven't got it passes 37 (Already had 3 wrong skills) but I believe at 43, 47, 54, 58 mark the skill will still be wrong.
