It mostly works, we stayed together most of time during FSD transitions. I can remember only once we cant see each other after exit from FSD, just relog fixed it. Problem was if one of us interdicted AI ship and other one synced to our low energy wake. We ended each with own independent local AI copy so we was unable to help each other. Was pretty scary when we wanted to jump on Anaconda. Maybe this is fixed, I ticketed that problem.
