OK, here i go
I made a gang, WeAreAwesomeness, with the name [RT]Muki
Then, i changed my name to Mookie (in the panel also)
Then, when i went ingame, and wanted to invite someone to my gang, i couldnt. It said i wasnt the owner.
Then i changed my name back and then i could invite that person to my gang
Thank you for your help in advance

Jato already knows this, or i think Nka said it to him.

Hello Muki

We are aware of this and the fix for it should come with the next update. Use the name you created gang with for now.
