I didn't know you had to pick that option, thank you for your help!
No worries :3 It's my fault for not making it very clear >.< I should maybe have put in brackets or something next to the choice (rename MC) or something like that so that players know to pick that option if they want to rename. Sometimes I have a habit of forgetting that just because I know something, other people can't read my mind and know it too x3
