Can anyone please give a hint with Recent events quest? At least, who should i talk with for proper quest update? Because i finished main plot, and about to leave to Onderon, but still have only that quest unfinished (and i don't like to leave anything behind unsolved). Currently, my journal indicates that i should learn more on person who leaked radiation. I know that it's Kaah, but not my journal UPD: Okay, i managed to progress with this quest. Now i have some issue when i ask maintenance droid to repair damaged recording. Screen going black, and that's all.
