The point of loading Railjack back to Dry dock to retrieve everything earned upon mission complete?

[--K--Sharkfin]

the content was launched almost a year, I am still scratching my head for why sometimes the loading is so messed up (holding you hostage for more than 10minutes) when any one of the teammates has a poor connection / high ping.

What's behind the loading and why is it so different to the normal missions? Why isn't there an option for us to choose stay or continue before the host launching the next mission? Why a random is able to drag the whole team back to Dry dock without the host permission? Why aborting after mission complete would lose everything including affinity earned?

Fun fact:
If you failed the last mission in chained missions (without going back to dry dock), all your previous missions completed would count as failed too, losing all bonus affinity and items you earned from the previous missions.
