[chris66nrw@…]

Hi,
some kind of background layers are not stored in the java session file (.joz)
when using the "save session" menu item.

Layer information:

Type: MVT
URL: ​https://hfs.githib.io/brandenburg-addresses/style.json

Greetings
Chris

Workaround: I'm adding the layer section manually by editing the session.jos file.

Yes, can reproduce. The checkbox to add the layer is always disabled.
Seems there is missing support for mvt layers in sessions.
