呵,空指针
问题要么是你模组版本不对，检查重装；
要么就是与“bergerkiller”（你看看有没有没有装这个模组或者包含/依赖这个库的模组）冲突了。如果你能找到那个模组就把它删掉；
也有可能是bug：代码没写好或者是你这个npc模组就依赖着bergerkiller，那就没办法了，向作者反映吧

都不行的话可以试试二分法查找，看看是不是与除了bergerkiller的其他兼容问题：每次删掉一半模组看看还有没有问题，没问题了就把刚刚删掉的一半模组中再删掉一半，往下继续；如果还有问题就把剩下的模组继续删一半，往下继续。这样以此类推。注意不要把你这个npc模组删掉，因为我们是在检查兼容性而不是单个模组

（非专业人员，仅提供参考，讲错勿喷）

已修复 是插件冲突

那就把前缀改成已解决，不然都以为你没修复
