Did the Casino DLC get removed or is it a bug?

Yes, Casino is still in the game. At least, it seems to be working fine for everyone else as far as i can tell. If you're not experiencing this, it may be a bug or an error related to updating to the newest build, or perhaps an incomplete install. Try validating your game files or reinstalling the DLC. If you're on a console, make sure to update your save. If all else fails, consider posting on the official forums with a screen grab of the missing content, so we can see what's going on. You're right that DLC is never removed, unless there's some big announcement about it. That said, feel free to submit a ticket through our game support portal, as well.

Is the Casino DLC still available in the recent releases? There could be a bug that's not letting everyone access it. Make sure you have the most current version of the game and all the latest patches. Visit the casino and let us know if it's working for you. Also check the developer's forum – they usually keep us informed about any known issues. If it's only affecting certain players, we can work around it. Either way, we'll sort this out together. Please let me know.
