0.14存盘加载后会跳出警示，且进入游戏后会无法进行操作
作者Tynan推荐的解法在此，需要自行编缉0.14的存盘(XML文件)，我测试过后可正常执行。

以下为教学:
============================================================================
Step 1) Using RimWorld Alpha 15, generate a copy of your Alpha 14 map (same
world seed, world size, landing location, and map size) and save it, we'll
need a few bits of data from there later.
先执行0.15版本，依据world seed、世界大小、降落地点及地图大小
生成相同的世界并存盘 (world seed 及降落地点可在世界选单中确认)
==============
Step 2) Open your Alpha 14 save in N++, find </outfitDatabase> and paste this
directly below it.
在C:\Users\[User Name]\AppData\LocalLow\Ludeon Studios\RimWorld\Saves中
找到你的存盘并开始编辑，将以下文字:

贴到标签</outfitDatabase>下方
==============
Step 3) Find <researchManager> and replace the <progress> section with this
