Accidentaly leaving Sasan the Bandit Lordencounter

Hello,

So I've had my Sasan the Bandit Lord encounter for the first time and my character instantly left the instance after entering it, it seems the portal is set in a way that makes it easily clicked by accident and lose all your precious workers. Can we have the same warning there's in heist that will prevent players entering the portal when they do not intend it? It was literally the most frustrating experience I've had this league, which otherwise is absolutely amazing.
