When Durant use Entrainment to a pokemon that mega evolves on the same turn, it makes it laughing around instantly, not the turn that follows it Did the test with Strudels on 3DS ( I found it yesterday by accident while messing around on the 3DS) and we also saved replays in case. It also works for the pokemons that have the same ability after mega evolving Worry seed then Entrainment does work but only for megas, as we tested for non megas pokemons and it does not work This is the bug on PO http://i.imgur.com/cbAOEkl.png
Elaborate on the Worry seed part. I'm not understanding the issue with that. I should have a fix for the truant one.
It was a test I proposed since I suspected it's possibly that changing abilities twice or more(either manually like Guts --> Worry Seed + Truant Entrainment, or via mega e.g Guts --> Skill Link --> Truant Entrainment) within a turn might be causing the Truant issue where you loaf around on the same turn you receive it. We disproved it though, it's really just Mega Evolution itself being weird.
