Part of today's update was removing duplicate worlds in the selection menu. Prior to this, Ciudad Enamorada and San Sequoia were my duplicate worlds; one version was functioning perfectly while the other would be corrupted to some extent.
The update deleted my functioning worlds, so now I'm stuck with the corrupted ones. The San Sequoia world is still slightly functional, but one lot has been removed completely due to one of the past issues with the For Rent save corruptions that messed up that world to begin with. Ciudad Enamorada is completely blank and unusable now. (Photos attached for reference)
Since these worlds have been present due to an existing issue for a while, I doubt there is a user fix that can address this, so I'm hoping a hotfix can help restore the proper worlds back to my game ASAP, especially since I can't even use one of them.

For PC/Mac this should be fixable by using S4Studio. I'm willing to help you fix your game so send me a DM with a link to your save game if you need help. If you want to try yourself and have questions, please post in the thread so I don't have to repeat myself.
