What I've found out so far is that after the latest update there is a plugin that interferes yours from working correctly. What I'm seeing is like the button on the oilrig has no handler. It is there but pressing it does nothing. When it works and you pressed it without the proper card you woud get a message but I'm getting nothing ... with or without the proper purple card. Also I'm getting no errors on the console.
When I unloaded all of the plugins except yours everything worked as it should. I'll see if I can manage to figure out which plugin is the culprit here.
