I'm not entirely sure what happened, but I'll piece together everything I do know.

During the end cutscene after defeating Therakiel on Elite, the map closed itself. The entire team was kicked out of the game (I was forced to completely relaunch the client, not sure if the others did but most likely). We did not receive credit for defeating him.

I for one have NEVER encountered this issue before, and personally it feels like a game function for mission maps that are empty was activated during the fight, without explaination. Based on the way it happened, I'm not even sure if there'll be crash data.

Has anybody else experienced this before? And better yet, is Cryptic aware of it?

Yes i would like this to be looked at if it can be.

This exact same thing happened to me and a cpuple of friends today. It is just BS with all these bugs that takes away all the fun, soon there is nothing left to do when you are lvl 40.
