Board Game Arena

I am coding a game that uses the showBubble function, but I don't think the custom_class parameter of that function is working correctly.
Where can I report a bug in a BGA package?

Thank you for the information.

I posted bug report.

I read your report and I don't think I understand anything. How you calling this functiion and what you expecting?
Custom class is added to the bubble on first creation, if tis already exists - its not updated
