Basically the title, fireteam ran through GOS, completed all divinity challanges, started the final boss enounter and entire team got "Contacting Destiny 2 Servers" before getting booted to orbit. Asked other friends outside of fireteam and nobody else got kicked from the game world so it was a specific crash in our run. Really would not like to have to do this again as it took a lot of time just for it to crash.
