Hi, not sure if anyone else has had this issue recently, but during a run of Legend Onslaught today, my fireteam got to wave 50 and had just started to tackle fighting the boss when I got a fireteam invite from a player who I didn't know, have never interacted with, and didn't know why I received in the first place, so I ignored the invite. Directly following that, I got hit with a Pony Error code and was immediately removed from the lobby, and returned to the title screen. One of my fireteam members got an invite from the same player and they too were removed from the lobby and back at the title screen. The last member of our group did not received a fireteam invite from this player but instead received a bungie friend request from a different player (Both players belong to the same clan, so we felt that it was somewhat not a coincidence that this occurred). This caused him to be removed from the lobby and returned to the title screen, eliminating any chance of us being able to salvage our 50 wave completion. We tried turning off our fireteam and social permissions so no one could invite/friend request us while we attempted another 50 waves, but during our second try, I was hit again with another Pony Error code, this time with no invites or messages incoming from any source. I don't know if there's any known fix or solution in progress to avoid having progress be impeded abruptly, but hopefully bringing attention to this issue can get it addressed faster before it becomes a more pressing problem. Thank you for any insight or feedback if at all possible.
