sometimes cave are empty. Also you meet one scorpion because Behavior AI was wrong because scorpions sometimes run with full speed at start so they run to edge of layout. "Also the cave feels a bit empty. Maybe add some loot? A corpse of unlucky traveller with some items, maybe, or a few chests with treasures?" yes i must figure out how place few things to loot and inside random loot. If humans will be in caves, i try add some symbolic fire. Soon i add full toxic caves to visit. Thanks for all suggestions
