[Bug] Download (built-in umap export function) is not working correctly: it only exports layers flagged as "visible on start"

By comparing the filesizes and content of downloads made using two different methods

• self-written nodejs export tool https://github.com/Wikinaut/getumap (3)
• the umap(built-in) export (1)

I observed substantially different file sizes:

different export files: export by umap(built-in) (1) vs. export by getumap (3)

Then I made a copy (2) of the umap (1) – using the copy map function – and manually flagged all layers of (2) visible on start.

Now and only then the umap(built-in) export function is exporting all layers.

Résumé: Users cannot export their maps in their entirety

This bug should urgently be fixed as users do not have any chance to download and backup their maps in their entirety.
