Bug with the end of the "Lake Trio" quest

[Ikumi]

Hello,

I just finished the entire quest. But Dawn isn't giving me the option to catch one of the trio's Pokémon. I really don't know what else to do.

Thanks

You need all non-legendary caught data for Sinnoh - not just the seen data.

Hello,

I thought the capture restrictions had been removed? I was able to complete other Legendary quests that previously required capturing entire regions, simply by having the data seen. Are you sure about that?

Thanks for your reply

Hey,

The Evo requirements have been removed. The caught data is mandatory for some of the quests.
And yes i'm sure, as this was changed last year.

Hello,
 

Thank you for these clear and precise answers. I was convinced that the Pokémon catching requirements had also been removed. My mistake. I know what I have to do! 
 

Have a good day!
