so I glitched inside a mission building in LEGO Marvel Super Heroes
title says it all
this is the uh Magneto + Mystique vs Mysterio mission and I flew Wasp super far away and when I tagged back to Iron Man he got stuck in here
at this point I didn't even have the mission unlocked, but when I did, I replicated it
You need to go into the mission then leave it, and during the SHIELD save icon, go inside the building. You can leave freely but after the icon is gone entering again will start the mission.
