Any servers using bricks with the following events do not work for me, ever.
onActivate - Client - Prompt - yes/no
onPromptAccept - Player - addItem - InsertRandomItemHere
Or anything similar that involves those two events do not for me on any server.
When I click Yes on yes/no Prompts, nothing happens. Yet, when I tell somebody that it wont work for me, it always works for them.
I don't know if it could be a Client-sided add-on, as I have deleted all of the ones I find useless.
