Still has not been fixed. Just tried, and I guess my BOP ship is not getting lucky with mines either. Engineer rank isn't high enough for eject plasma core to be useful. Really hope it doesn't take as long to fix, as they did with that one romulan mission (to help or not help Obisek).
So far no updates had been made. Social media said the issue was resolved, but that was 10 hours ago. i'm having the same issue as well, and I haven't seen/heard any updates yet.
They posted on social media that some rogue, section 31 agent, sabotaged the servers...they said they brought it back up....probably wasn't fast enough, and Garak got bored and started tinkering.
Just tried to login a few minutes ago, and it shows "up" but good luck getting in. You either time out, or get in with no way of doing anything. Have we heard any updates from ARC?
