Just sanity checking, has anything important changed between Relume -> Webflow in the last few days? I'm constantly flooded with massive numbers of duplicated classes all of a sudden. Completely unable to import a site without 9+ versions of ever core class. I'm using the same styleguide that's been in place since March 2025 and Relume shows that one as still being the one to use so I'm not sure if something else has happened in the pipeline

Adam B. yeah unfortunately there is a real possibility that something has changed on the Webflow side. Unfortunately we don't have much (if any) control over what they do with their endpoints or source code. Though, they do tend to consult with us and we try to collaborate as best we can. Specifically though, I have not heard of anything around class sync that could have changed. One thing to try to do would be to disable the real-time collaboration in the webflow project under site settings > general (bottom). Let me know if this does the trick or not. If it does, it might be related to some other bugs we are seeing.

Thanks Matt J. I'll give that a go on the next one and see - I opted in the end just to import the style + home page and rebuild the rest manually. I've had issues before with class sync when pasting straight in but I tried the full site import on fresh templates several times over and couldn't seem to get it working. Bit weird, usually it works fine

I did check though, I had the Relume addon, class sync enabled, fresh template etc - all had the same issue. Also any components in my design got dropped after the first page they were used in, so navbars/footers etc went missing

hmm yeah seems like other things are going on - is there any way you can record your screen as you are doing some of these actions - I think thats the only way for me to get the full context and picture of whats going on.

I do know of at least 1 or 2 classes that consistently will duplicate, but haven't seen or experienced having a lot of classes duplicating. The navbar/footer thing, are we saying the entire navbar/footer is missing completely on import or? If its just that its not coming in as a global webflow component (green) that's a limitation of Webflow and not something we can control. I also have heard that some chrome extensions can have adverse effects on class sync in some cases. So maybe that's an issue. So yeah, as you can see, there's a lot of variables

Adam just did some testing and had the same thing happen but it was on the last page imported and there doesn't appear to be any rhyme or reason as to why this happened....massive fail too. Duplicate classes on a bunch of divs, it straight up didn't bring in the global styles component which it should, etc. I'll have to do some more digging to try to reproduce this one....could be pretty tricky and lengthly to get fixed unfortunately.
