Automatic "detach instance" ruin my file

Some weeks ago, I noticed that all my instances have detached themselves from their parent’s composant with no reasons, asking me a big amount of time to recreate each instance.
And it happened again. I don’t understand and don"t find any similar case in the forum.

Any idea about how it happens and how to fix it ?
