DC on party screen, still displaying i was in the party, but i wasnt.

I was in a lobby (team builder) with some random guys, i joined a curse voice call they posted, but i didnt really talked too much since i was checking other stuff. Thing is, i got a dc message from server, lasted a few secs, but i was always in curse, so there was no internet outage in my part.

Anyways, i thought they were watching a stream or something since i wasnt paying too much attention, but turns out my screen was still displaying that i was in the lobby, but they were actually playing already.
