...but tribble server is not always "charged" with players, so it's difficult to say how Holodeck can react to new missions, planets and mark system when implemented.
As far, the only issue I found is that, when returning in new romulus after disconnecting, you risk to be stuck into a stone when appearing on the surface...it happened 2 times to me.
Other issue can be finding NPC in the great new romulus map...it's not so easy if they are too far. I had no problems finding all of them, and I finished almost every mission, but I saw many people wandering around.
These are minor "bugs", if they can be named that way, so I hope that season 7 can begin soon.
