Tried to run the the Terradome again last night.
Got into the final boss room, killed boss, then Sulu died and the failed mission pops up.
NP, we thought we'll just try again. ... Only to find all the Sulus were now invincible..
So it would appear killing stuff out of sequence will ruin the group.
Youll be able to pick up the boss loot (purple stun pistol for us last night) but you wont get the mission credit, or be able to reset the room and try again without invincible mobs.
(we tried zoning out / disbanding / reforming etc, but it didnt resolve it)
That issue is known in other forum threads; except for the "Camera bug" and the "Only be abble to go front and back bug" after a reset (both will go away like after 30 secs or so) I have not encoutered any bugs. But they are out there.
