If you have a bug you'd like to submit to the development team, you can do so here at our Terraria Bug Submission Website.

Simply fill out the form with as much information as you can (the more, the better!), and it will automatically go into our database for testing.  From there, our teams will communicate out updates on which issues are being addressed every couple weeks.

Need to know the latest bug fix status?  Check them out here:

The Developer News & Announcements section on the Terraria Community Forums (TCF) is a great general resource where we centralize all of this information and other announcements.
