This is also weird... Here's what happened...
With some help, I cleaned out the defense platforms and the defending ships, then the base. No problem there. When I destroyed the last defense platform, I get a dialogue about my XO going off. I guess she's leading the demolition team personally, heh? But I don't see any away teams to beam down either! Then the dialogue says "energize", even though I'm still range 8 or so!
Then I went to transporter room, and noticed an away team! However, I can't beam them to the planet! I approached within RANGE 3, but they won't beam down! And I'm out of marines! If I keep hitting the planet, eventually planet goes to ZERO health, but you can't hit it with phasers any more, and it still has shields!
Ack! Any one got a sequence that actually WORKS?
