I feel a little dirty adding to this sea of support tickets, but…
After about an hour or so of forging, the map will no longer save. A nice surprise after not saving for a while. Happened three times so far.
:!
Potentially significant factors:
-Lightmap was above ℅70 each time.
-All the same map
-I’m pretty Liberal about rebaking lighting
-Alpine map; overcast; fog effect; cloud shadows
-All primitive objects and structures (plus some warthogs and mongeese)
-A few large groups of large objects
