When i was testing for the first time i've got the same problem, but if you read carefully the main post of the plugin, where it says how to install it, he/she said, that we must put a script call in the intro event, so the script can begin working properly. In the script call post this: addAllBadge Then, when you open the badge case it will work.
EDIT: roei110 if we call the script: pbGetBadge("BOULDERBADGE"), with the " in an event it works, but if we trigger this first: addAllBadge. Otherwise it will give us the errors. Please, update your main thread, this part pbGetBadge(badge) into pbGetBadge("badge"), so people can know how exactly to call it in events. The rest is working fine.
By the way, i noticed that the badges will not be listed by order, they will be listed "randomly" for ex: the first badge is boulder badge in my game, but if i "obtain" the volcano badge first, this will be the first badge in the badges case, so I'm guessing that the order of the badges doesn't matter now, am i correct?
