Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Just checked in the Smogon Wi-Fi server, it seems the name change is done by trading it at all in Gen 7, for it to keep its OT it'd have to be given in Gen 8 or HOME.
If that is the case, then game freak really messed up its consistency with the shiny tapu event Pokémon, but then again this is the same company that could not be bothered to fix shiny nidoqueen and make it purple like it’s preevolutions for so long.
So only in gen 7 will the shiny Tapu Bulu OT be either Moon. Or Sun. This includes Ultra Sun and Ultra Moon. The OT only changes to Ula’ula OT in gen 8 or home?
Well, it seems the rename is permanent, transfering it to other games/languages by then shouldn't change its OT back, in any case it seems accepted in legality either way given it's obtainable in-game, like the whole shiny Mapaphy incident.
I meant if I restart my ultra sun game, which I am comfortable doing, could I change the language to Spanish and you generate another Tapu Bulu just to see if that will undo the glitch? I just want to try it.
Turns out that will probably have to be the case, it seems my 3DS Micro SD card is having issues and I'd rather sort it out to avoid potential data corruption.
Okay, I do not mind waiting as I just want to try restarting my Ultra moon game as I have no important Pokémon on it and change the language to Spanish just to see if it will fix the problem as the Reddit post said. I assume the sd card is where the wonder card data is stored, could you buy a new sd card and put it in your 3ds?
Well, first I have to check if it's something I can fix on the software side.
And yes, all save data of 3DS games are stored on the SD card.
If it fails I'll probably be unable to as I have a lot of stuff into my SD card and so wouldn't be easy to replace.
