Yeah, that kinda goes hand in hand with the “similar name” problem that I referenced. I have a feeling that on the guild creation event, they do a “pluck” on the field (which stores the name in the database as for example: TombRaiders instead of Tomb Raiders). This can help with validation on empty fields and storing them as nulls in the database instead of empty strings, however, when the data is taken out of the database from the server back to the client, there’s a good chance that it compares guild “A B C D E” with guild “ABCDE” and not recognize the difference.
This has happened before on a several occasions that I was involved in.
