* Compare to ITEM_HM01 and not ITEM_TM50
While both compile to the same output when doing test functions in https://cexplore.karathan.at/, shinny pointed in the discord that, if you expand TMs, using ITEM_TM50 would break things.
This was the previous behaviour but was changed by cbt when documented the party menu.
This was pointed out but HunarPG in the pokefirered Discord channel.
* Use ITEM_HM01 instead.
