I used an exotic cipher tonic and shortly thereafter (about 10 minutes) I was no longer able to matchmake to anyone. No matter which activity I joined I would end up in it solo. I even tried to use fireteam finder and it would not let me join that fireteam. My internet was working fine and our other system was not having any issues on other games. What would be the likelihood I would be able to have anything done about this. If it wasnt for ciphers I wouldn't care so much. But they are hard to come by for me.
