关键是场景直接被破坏，场景.fire里面的数据全没了，这不是坑爹吗。还好做了git，不然岂不是要哭了

#3

我查看了源码不可能是这里的报错，你是否自定义了引擎？能给个重现方式吗？

#4

1.4 版本开始场景数据会有更好的处理方式，应该不会再丢失了。

#5

1.4大概什么时候出啊

#6

今天我也升级到1.3.3 遇到这个问题，终于我回退了N个版本和比较，解决了，快吐了。。。 我给你说下我解决的问题， 是我用某个元件生成了prefab，这个元件在场景中继续使用，就出现了这个Cannot read property ‘_prefab’ of null 问题，如图所示

解决方法是先复制，然后再删除之前的元件，就可以了:joy:

#7

没有修改过引擎，私信给你githup地址，有空帮忙看下

#8

抱歉我用 1.3.3 未能重现这个问题。是因为要从旧项目升级上来才行吗？能不能更详细说明一下重现步骤呢？

这个元件指的是节点吗？节点在场景中继续使用是吧
