Because the string "(Still in Guild)" is hardcoded, the only way i found to use the "Remove Ban" button is changing the locale to English.

string.find ( fullName , GRM.L ( "(Still in Guild)" ) , 1 , true ) ~= nil then

I just swapped a bunch of languages and didn't have any issues. What language are you using so I can try to recreate this.

I can probably write the parsing better anyway with some regex, now that I look. This is some pretty old spaghetti code lol

Alright I have this fixed in my 1.988 build. I'll release soon, just typing up changelog.

ok, I was using French language.

I am happy that my comments are used to improve this excellent addon =)
