#knownfeature and maps; aka "the Disappearing Act"

Use #killfeatures first. Random sites are assigned first, and any #knownfeatures that are added after the fourth total site are ignored. If you get one of three #knownfeatures, the province already had three sites etc.

Ah! Of course! Thanks, that will probably work!

Just one question, though; Will this prevent future random sites? Say that I do:

#setland 111
#killfeatures
#knownfeature "Howling Gorge"

Will this prevent me from finding future, random sites? Will I actually have to assign #feature to find something there, later?

Again, thanks.
