Can't open lot / screen stuck

@flyugyeom Do you have any LastException files in Documents\Electronic Arts\The Sims 4 ?

Best is to delete the ones you have, then trigger the error and check if new ones are created.

If that is the case, please upload them to a new post in this thread.

Please either create a .rar file to upload or copy/paste the content into your post.

Deleting the file won't fix your issue. Uploading the file is meant for troubleshooting.

@flyugyeom Install this mod: https://www.patreon.com/posts/mod-milestone-81237568

Start the game with the mod installed and then load the lot. This should fix the issue.

You can remove it afterwards.

@crinrict It didn't work, the game still went unresponsive :'(

@flyugyeom Did you download the cc fix ? file 2 (thought I specified)

Are you still getting a new exception ?

@crinrict Ok so I did as you said with the right file and still no change. This is the most recent last exception file. Thank you for trying

@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.
