Yeah, I meant the asterisk. Doesn't matter if it's Cristallo* or Gold* or anything with an asterisk; it says it's using invalid characters. Removing the asterisk from Cristallo in particular then results in an "OT Name too long" error, as it's over 7 characters.
Most likely just need to compile a table of acceptable names to check for, if the Gen 1/2 flags as well as the asterisk are present.
