This affair must have caught Liam at a bad time, fretting over the echos of the many Valiant kills permeating the comms. When my Valiant appeared on radar, Liam knew he was dead before he was dead.
With the release of the Alpha 3.13 patch all previous reputations and bounty certifications have been reset. One of the first certification you will encounter is the Tracker Training Permit Certification. You can tackle this certification in any nicely equipped light fighter.
I like to keep familiarity with the Gladius, in my case the Valiant, to keep sharp in the fighter that will no doubt be your starter ship in the upcoming Squadron 42 adventure. Best guess is that we will see the release of Squadron 42 sometime next year.
