Not able to join or host sts-25 Tarasa colony

[Admlucero]

I noticed that whenever I am playing sl that I cannot play sts-Tarasa colony. It doesn't let me click on join/host whenever I want to do those things. I have talked w/ my guild and they aren't sure what is wrong either. Thank you for your time.

only Champions of Blackstar can do that
kill the boss in the 3rd map of that campaign to gain access to Tarasa

They've fixed the bugs,

You need to kill Numa boss on 3rd map (Twice Scorned?), and be lvl 45 to join.
