I have a strange issue here. In this world I have been playing in, when I start an adventurer and play for a little while, underground life starts vanishing. The world starts with the normal underground population. After a few days of adventuring, numbers drop sharply. This includes all cavern life, magma creatures, cavern and magma vermin. Only clowns are left.
If I start a fort without adventuring first, underground population drops only slowly, after several years, as would be expected.
This happens even without discovering the underground in adventure mode.
Any ideas?
Is there a way to get underground population back via save game editing? I have no idea where/how population info is stored...
This is in a pocket world in an unmodded 34.07.
