Hidden Power is broken

[killemall420]

I don't know if I'm the only one who noticed this, but whenever I put a Hidden Power type on a Pokemon like say, Kyurem-Black with a physical and special attack and then save my team, it drops my IVs to 30, even though I'm on Sun and Moon, not ORAS, BW, etc. It makes it impossible for me to use Pokemon like Mega Diancie correctly and I'm super frustrated no one has fixed this yet.

Some screenshots showing the problem here:

When I give Mega Diancie the moves

Then I save my team

This happens

And Showdown says its just fine

Obviously this isn't just a problem with Mega Diancie, the same problem occured with Greninja as well.
10/10 needs fix
P.S. I'm using the app, however I tested this on the browser and the same thing happened there so it's not just a problem with the app.

I've found a related bug, but I can't reproduce this exact issue.

Can you give step-by-step instructions for what you do to make this happen? Preferably starting from opening an Incognito/Private browser tab and navigating to PS.

Tried in an incognito tab, was able to reproduce (Chrome 61.0.3163.100, Windows 10). Steps are as follows:

• Visit https://play.pokemonshowdown.com/teambuilder
• Create new team (I didn't select a tier but I don't believe it matters)
• Select Diancie-Mega and set Ability to Clear Body
• Add Diamond Storm in slot 1 and Hidden Power Fire in slot 2

At this point you can observe that all IVs are listed as 31s

• Click Import/Export, then Save

IVs are now changed to 31.30.31.30.31.30

Okay, I've got it, thanks.

How is this a bug? It's intentional is it not?
This is how the type of hidden power has always been decided on, it's based on the IV's of the pokemon so when adding hidden power of a specific type it must change the IV's to a valid configuration or else the move will be illegal.

The only hidden power that works with 6 perfect IV's is Dark.

@killkrazed I don’t believe that’s the case in SuMo

Bottle caps in sun/moon allow ivs to be boosted to 31 while maintaining the existing HP type, this is because it dosent actually change the IV in game (so it dosent effect HP type or breeding), but simply makes it act as if its 31 in battle. This is implemented on PS by assuming that if an iv is 31, its bottle capped. So a pokemon with 31/31/31/31/31/31 ivs can technically have any HP type.

close?

[HoeenCoder]

I checked, the issue isn't resolved.

oh ok, I could have sworn it was fixed by something... :|

The main problem is that we currently don't save generation in import/export, and we need to know generation for things like this.
