This has been an ongoing issue for over a year for me, and I honestly can’t pinpoint one set example of the bug.
I’ll work in Webflow for a few hours and the site seems to save as expected. Then I’ll make sure my site saved (green check confirmed), publish, and close out of the Designer tab. The next time I return to work on my site I often find some elements I was working on in the final 5-10 minutes prior to saving the site simply won’t have saved. Things such as a color background that I set, a border, text coloring… etc etc. This also happens at random times while working on my site.
I suspect this bug is due to my internet connection temporarily lapsing and Webflow not recognizing changes I made during the time I was disconnected, but I would hope upon reconnection Webflow could save the intermittent disconnected changes. Sometimes elements in the designer on the right side won’t even be clickable after a lapse of connection and I’ll be forced to refresh (even after a solid connection has been re-established). It’s a small nuisance more than anything, and I thought I’d mention it.
