This is GamingWildlife on my other account.
I do not have the Coruscant Mod nor have I even heard of it. My quest tray had 3 items in it: Trade Route mission for Geeda on Nar Shadaa saying I just have Onderon left, Lost Jedi saying that Kavar will contact me when ready, and Master of the Palace also saying I must wait for Kavar to reply.
I had another save where I tried doing Korriban last instead of Onderon, but the only difference is that Lost Jedi tells me Vash is on m478 and that I can travel from the galaxy map, but HK's dialogue says I cannot go there at all until I advance the plot
