How to replicate this bug:
1.Get a Pokémon with steel beam i use Heatran for my example.
2.put steelium-z onto the Pokémon.
3. go into a battle with any wild pokemon and activate the z-move.
4. now you will see steel beam is still their even though you activated your steelium-z in the battle menu. this should be Corkscrew Crash.

Tested in 9.1.9
-Used a Heatran with Steel Beam and a Steeliumz and steel beam was not recongnized as a Z move
-Used a Heatran with Metal Claw and a Steeliumz and Metal Claw was recongnized as a Z move

Hi there,

I can confirm that Steel Beam is missing Z move data from its move definition as of 9.1.9, which results in it not reacting to the steelium z you've given the Heatran to hold. I also found some other moves which were missing z-move data in a similar fashion, the full list of which can be found here.

Moving to internal now to be resolved, thanks!
