That's just "mansion" being "mansion"... huge, elaborate and taking for-fricking-ever to load.
The "error message" on the geoscape is just the default text for a new map. That should be changed by the mapper sometime to reflect the actual map.
Polite as every time. Thanks.
I added the description string in the map definition.
Also, on my System (AMD Athlon(tm) 64 Processor 3700+, 2 GB RAM. Win XP) it takes not even 2 minutes to load, wich I think is a small price for what you get.
(Actually, I remember, once upon a time one had to wait more than 10 years to buy a car! Thats something I would call 'for-fricking-ever'.)
But good news : I am still working on some "small" assembly, wich will reduce the size of the map and thus loading time.
