I was running the Nightfalls this week and had major issues with the same error code. Every time I use the Riskrunner MP and the exotic perk is active, I get kicked to orbit with the error code „bird“. It is a 100% replicable error and occurs when the ark chains of the exotic perk kill too many enemies in a short amount of time. Only happens when I use Riskrunner and only when there are masses of enemies which is the case lots of times during this Nightfall with waves of enemies entering the small rooms. I got kicked to orbit lots of times and really got me upset. I also noticed that other players using the Riskrunner also got kicked during the activities. Please advise. Thanks in advance.
