Try copying the save file and pasting it into the lastest experimental. You might get it to work. If not, if you really want to export your character, perhaps play around with the maximum trait points and give a new character all the attributes of the old.
Personally, when I got bored I started a character under rules that contrast with the increased spawning factor, instead making it more difficult to survive the daily grind. From the default, make these changes:
[ul]Debug:
[list][li]Default. If you are getting frustrated, turn max trait points to 16/turn skillrust to intcap.[/li][/list]
World Gen:
[list][li]Mods to use: Medieval (not for weapons, but armor options), Old Guns (see gameplay as to why)[/li]
[li]Size of cities: 1[/li]
[li]Item spawn scaling factor: 0.33[/li]
[li]Spawn rate scaling factor: 0.5 (less enemies means a tougher time finding items on corpses)[/li][/list]
Char Gen:
[list][li]Required Trait: Meat Intolerance.[/li]
[li]Required Trait: Junkfood Intolerance.[/li][/list]
Gameplay:
[list][li]Required playstyle: The things you have an intolerance of are things you are not allowed to eat at all. You’ll find that wheat is a gift from the almighty.[/li]
[li]Required playstyle: When fighting you may only wield your bare hands, weapons that fire paper cartridges, and thrown splash items and explosives.[/li]
[li]Ultimate goal: Craft for yourself a flintlock. This is much harder than it sounds, since towns are almost always just 4 buildings, usually houses, often with next to zero zombies. The tools you had taken for granted: forge, swage and die, even the hammer, Become woefully difficult to find or craft since you’ll have a tough time getting them in even public works locations and crafting them without their corequisites.[/li]
