Problem adding a closure on newly modified segment

When trying to add a closure on this segment: https://waze.com/en-US/editor?env=row&lat=55.72253&lon=9.13443&s=1235931901595221360638&zoomLevel=16&segments=450867938
I get following message: “Oops! It looks like someone else changed one or more map objects you edited before you saved”.
As far as I can see nobody else has worked on this or connected segments.

Hi, as I can see this segment was created recently and it split this segment:

So you will be able to add closure only when the next tile build is finished (cause closure can be added only to segment that already exists in tiles).
