Mansion map battle-scape is being hanged with a message "please wait" - which never go away..
mouse stuck - keyboard input non-responsive.

Due to: Not enough spawn points?

Behavior:
1. The map was loaded.
2. The briefing pane showed.
3. I could move and explore the map with keyboard and mouse when it has focus on the map.
4. upon clicking the ok button on the briefing panel - the "Please Wait" message in red appeared.
5. Game Frozen.

Is reproducible: Yes.
Data from game console consisted two warnings of invalid tiles in the map before it is stuck.
