web version can unfortunately be a bit unreliable and prone to this sort of breaking. We have a few potential solutions to this (copy-pasted from the discord):
What you can do to fix it:
1. Make sure the website isn't down: The website should go to a 404 page upon a contributor attempting to push any update of the sorts.
2. Try leaving the site: because there might be a lot of people trying to get in. Just exiting out of the website for a while might help boot up the page upon re-entering. You might have to wait 30~ minutes, but it should be the first thing you retry.
3. Convert your save: If you have an older version of your saves, which predates the update of 12/25/2022, you might have to convert your save to the new save-file format. Use https://clangen-web.github.io/convert.html to convert, then refresh or completely exit out of the website.
4. Use a different browser: Some websites can only work for some browsers. Change your browser to see if it works.
5. Use an incognito tab: Sometimes it works if you make your tab incognito
6. Clear your Cache: This should be a final resort if all else fails, clearing your cache completely deletes all save data:
