The problem persists after the update. this is the number of dublicates in the newly generated feed.

The problem still only occurs after the feed updates, the first feed generated on a clean install has no dublicates.
I will give the new update a shot and get back with the result.
Thank you for the super fast and detailed replies! solved
The demo just shows what it looks like, can you confirm what this timeline feature is avialable in the frontend too, with no login or such thing. 🙂
