Yellow Server Guild Creation

[Xalamance]

I understand that over the course of the game, many guilds have been created and many simpler names have been taken from the guild name pool.

 

But it doesn't make any sense for guilds to be created on yellow server with the names Kappa and Tranquility, but names like HarmoniousElite are "taken"

 

I have 205 hours, have completed hoenn region, and more than enough poke to cover the guild creation cost

I have the same bug no matter what i try it says: This guild name is already taken.
