Map shows old/new details at different zoom levels..

The first thing I noticed with this latest render was that my latest building was missing, even though some new builds could be seen.
Then as I adjusted the zoom levels around an area I knew had changed I could see a waterfall when fully zoomed out however it is no longer there and this is rendered correctly as gone as I zoom in. The location is near the tower at x=820, z=-1200.

There is a similar issue at x=400, z=-1110

It looks like the latest changes are only reflected in the most zoomed in view.Undecided

Given a new clean archive it seems hard to understand how old and new features can appear on the same render, in the same chunks, unless there is an issue with the rendering?

Sometimes this is your browser caching the images so you don't see the new updates.

Clear your browers cache and you shouldn't have any issues with seeing the latest version.

Yep, that fixed it. By the way, browser is Chrome.
