So, I recently attained lvl 10, and I tried going to Starbase 24. I get to fight all the ships with people... but when it's over, I can't figure out how to beam down to the station to start the ground segment of the mission.

Is anyone else having this issue? Has anyone figured out how to get down there in a way I haven't thought of?

same thing just happend to me. we defeated all the ships but couldnt beam to the station. nothing after we defeat the Neg'vars

I can "attempt" to beam to the station right after killing the 50 ships, but is canceled by 50+ Neg'vars spawns and their 3-4 linked cloaked escorts steam role over the entire fleet.

Same here. We defeat the 50 ship's and can then attempt to board the station, but the neg'vars appear. I've tried hailin butt and bypassing the neg'vars to get to the station, but even then i dont receave and access to beam over to the Starbase. You must attack and defeat the Neg'vars, thats it. After you defeat the Neg'vars, the mission is over, but I still dont get credit for completing the mission. Everytime i test this, I have to manually drop the mission.

That problem's been on Holodeck for a while now, as well, so it's not new to Tribble.
