Re: Can't open lot / screen stuck

@flyugyeom That error means that you removed some CC that gameplay had associated a milestone with. Lumpinou's mod called Milestone Fixes does fix this problem. Make sure that you have the newest version and that it's not too many folders deep in the Mods folder. If you want a double-check on whether it's the right mod properly installed, you can follow the instructions in How to Use Mods and CC on making a text file of your mods and attach that file to a reply.

Putting the right CC item back in the Mods folder will also fix it.
