Custom part and disconnection

Hello,

I ask this question because this has happened several times and I can not find the solution. (Sorry if this question makes duplicates somewhere where if not the right section for the question) Between friends we create a personalized part and sometimes one of us is disconnected (micro cut or other reason that does not matter). The disconnected player is therefore replaced by an AI. Is there a way to get player deco to be able to return in the game? Thanks in advance for your attention to this post.

Regards,
