Unlike The Sims 3, TS4 is pretty good at keeping the town populated, in my opinion. There are more than enough new townies in each generation for my Sims to find friends, enemies and partners and to prevent the town from stagnating. There's a slight problem, though. Vanilla TS4 includes a population limit of 180 Sims. Since this includes dead Sims as well as living Sims, anyone playing for a long enough time will usually reach the limit, at which point the game will begin deleting any new Sims that enter the town, making the game pretty much unplayable.
The game is also programmed to "clean" the genealogy of your played households, meaning that it will also delete Sims that are distantly related to your Sims for no other reason than you haven't played them in a while.
This mod stops both of these forms of culling.
This mod will disable the "Max Population" and "Genealogy Pruning" story progression actions, preventing any Sims from being deleted by the game. The game will continue to generate new townies even when you reach the 180 Sim limit and they won't be deleted, either. EA implemented these features to improve the game's performance, but as most of the Sims in your town are either dead and/or inactive at any one time, I don't see any notable consequences to disabling them.
This mod was based on game version 126.96.36.1990 (December 16 patch) and will not work on any previous version, as the patch introduced new story progression actions related to Outdoor Retreat that are not in the older versions.
This mod edits the StoryProgressionService XML. It is incompatible with MisterDinadan's NoGenealogy mod, but this shouldn't be an issue as my mod incorporates the same functionality.
该Mod编辑修改了StoryProgressionService XML文档。与MisterDinadan的NoGenealogy mod冲突，但并不会产生问题，因为这两种Mod的修改方式是一致的。
Unzip the archive and place the .package file in your Electronic Arts/The Sims 4/Mods folder.
解压缩，将package文件复制到C:/我的文档/The Sims 4/Mods文件夹。
The no genealogocide mod also won't work properly if you have Outdoor Retreat installed as the December patch added some new story progression actions that weren't there when MIsterDinadan made his mod.
上文所提及的no genealogocide Mod不兼容Outdoor Retreat扩展包，因为MIsterDinadan（no genealogocide Mod作者）制作该Mod基于的游戏版本未加入12月份更新文档中包含的新故事进展程序。
