That's a hard coded game mechanic. So nothing to do with the scenario either way.

I've read in the recent patch that players can log out in seats now, which is HUGE for multiplayer, seeing as trying to meet up with my friends all the time in other parts of the galaxy is what eventually ruined it for us. Does anyone know if that is enabled here in RE2, or will there need to be an update before that feature is active? Been looking for a reason to get my friends back into this for awhile.

This is from the devs in their patch notes regarding this function:

"Note: For those who noticed the 'log back in to passenger seat' feature for passengers returning to the vessel in MP/Co-op on our experimental branch, we have temporarily disabled it for this release. This is due to an issue we discovered and need to address before making it available. We will provide an update as soon as the issue is resolved."

So currently NOT available.

Thank you X 2
