Wilian started a meeting with x-ray density maps on one computer then joined it on another computer. The second computer did not have the maps locally and showed a dialog to replace the map file. Clicking cancel gave this error. First should fix this error. Next fix the meeting command to always include the maps when sending a session to a joining party. For big map files might want to have a meeting command option that says that remote parties will have their own copy of the map and not to include it in the session file.

Fixed.

Replacing maps when restoring a session was broken when map surfaces were made separate submodels.

Made meeting command include maps when sending session to meeting participants.
