MrXiaoM

全是空指针异常，全都不知道是什么字段又没被检查是否null就使用

第一个是在处理战斗包，发战斗消息出去的时候出现了空指针异常
第二个是特殊的攻击中，添加效果的时候出现了空指针异常
第三个是发包的时候出现了空指针异常

完全没头绪，然后我翻了下宝可梦重铸的更新日志
Remember to delete the Pixelmon configs and any of Pixelmon's external JSONs before updating to a new version. See: Updating Pixelmon - Pixelmon Wiki
近期你有升级你的宝可梦mod吗，升级的时候有遵循这句话删除宝可梦的配置文件吗
