请问，在新建的项目中是否会有这个问题。

#3

反复确认了一下，是在2.1.2里面拖任何节点成为prefab就会报错。。

#4

试了一下，新项目不会有这个问题。。我是从2.0.1升级过来的。
现在项目不操作，停一会也会出现同样的报错:joy:

#5

用2.0.1打开之前升级备份的项目，好像拖着拖着也会有类似的错误。。一般是什么情况引起的？

#6

根据这个报错，还无法定位到是哪里出了问题。你要不新建一个prefab，然后和你之前的prefab对比看看除了独有属性之外哪里有异常？
或者试试把assets拷贝一份，粘贴到新的helloWorld项目下。
再重新打开试试。

#7

反复定位过之后，发现某个节点挂载的script节点坏掉了，没办法删掉。我把整个节点删掉之后，就不会有这样的问题了。
感谢一直回复哈

#8

我来更新这个问题,最近一次想拖拽几个节点作为预制体,然后复制到另一个节点上去,不知道为什么没有粘贴上去,返回后将节点还原成普通节点,之后就出现类似报错,经过排查发现有个操作过的节点下的子节点父节点id不对,随后重新将该子节点拖拽出当前父节点,然后拖拽回来,子节点_parent id,更新,错误解决!
