This actually isn't a bug, though the error message is a bit confusing. Shiny Tapu Koko is event only, Non-Shiny Tapu Koko is not as it is catchable in-game. If your Tapu-Koko is shiny it must match the event where it was shiny, your set probably has moves or something that is incompatable with its event.
It's not the moves. I said I put on only Tbolt to make sure of that. It can learn it via tm and have the other moves deleted in game so that's not the issue.
That appears to solve the issue. I was unaware the event was timid only, but this still means the error message needs correcting, as other Pokemon (eg Genesect and Entei) correctly say what nature you need to match an event, whereas this error message with Tapu Koko incorrectly says the issue is that it's shiny, as opposed to that it needs a specific nature to match its event.
This is most likely because with the shiny events for Entei and Genesect, they have exclusive moves like Extremespeed. The team validator prioritizes factors that actually affect Pokemon like move-nature-ability compatibility, since in that case, you may want either factor over the other. However, if removing/adding shiny is the easiest way to make it legal, it will only mention that.
The sim classifies this as an in-game event, to distinguish it from catching a wild Pokémon. In this case it means that it must be at least level 60 and cannot have its hidden Ability.
Not just Entrainment. Any way to change the ability to Truant in the same turn it Mega Evolves (an even easier way to cause this is Mega Alakazam Tracing Truant) will make it loaf around in that turn.
This is how it works on cart. When a Pokemon with Sheer Force uses an attack that is affected by that ability, the opponent's Emergency exit won't trigger. It's similar to how Life Orb isn't triggered in that scenario.
Actually it's more similar to Eject Button, but it's the same idea.
Minior, while in Meteor form, cannot be affected by any status conditions due to Shieds Down.
In fact, if we want to go strict, Yawn should have outright failed, as that's how it works in cartridge.
Lickilicky's Cloud Nine.
Ah, thank you. I spent like 15 minutes trying to figure out why lol
When Gliscor uses Roost, it removes the flying type of it for that turn. Meaning that it becomes weak to Energy Ball because only the Ground type of Gliscor is taken into account.
It switched out and Traced Water Absorb after that
