Shadow in Raid the Vault after end

A Shadow has been inside the Immortal Vault for more than 1 hour after Raid the Vault ends, and does not leave.I’m monitoring with an alternate account in the shadows, and they are standing there to advance some time later.

We were on standby yesterday and the player attacked after 30 minutes, now 1:27 hour, this practice is very abusive and happening every day, please limit the maximum time a shadow can stay inside the Vault, I don’t want to stay online all day watching players without nothing to do with they time.

Thank you.
