Umbra attacking and making specters hostile towards the player

[(XBOX)golden shootgun]

So I was playing and infested defense mission and I decided to deploy a shield drone Spectre in operator mode to protect the reactor as soon as I did so Umbra decided to shoot it and it instantly tried to kill me so I shot back and killed it, so I tryed to deploy other specters to see if he would do the same thing and if they would attack and they both did. I I tried every Spectre in my inventory to see if they would fight him, even the specters of myself begin fighting each other and me. I just want to know if anyone else has experienced this because if so this needs to be fixed immediately cuz this can be severely exploited for EXP/affinity

While specters issue should be fixed, it can hardly be called exploitable. Who would spend resources for minor affinity gain you can as well easily get for free?
