Weird bug in mid-conquest

[Anonymous Spoy (Steam)]

So I was just playing through the campaign "Hunt for Zsinj" and fighting, conquering, etc., and I went through a ground battle on Dathomir. After emerging victorious, I was shocked to see that one of the enemy heroes that I had fought was still showing up, and I couldn't take the planet. At first, I loaded the autosave and refought the battle, thinking it was a one time glitch, but it happened again. I shrugged and dragged my ground fleet down, and BOOM! Instant game crash.  Music kept playing, but I couldn't do anything more to my units, although I could still move my mouse, and I couldn't move around the map anymore. After a bit, I ended up using task manager to end it, as it had frozen. I have no clue how this happened, and as I am writing this am preparing to return to (near) the incident's location and see if it happens again. Any help would be much appreciated.

So, after much re-battling (my bad, I forgot to save for an hour or so) I made it back to the same planet, Dathomir, and the same fight. After having finally  finished the fight again, I can officially say that this isn't just a onetime bug. It's a campaign bug, at least for me. The hero's name is "Melvar", and he is stuck on Dathomir for no apparent reason even though I watched him be destroyed by my troops. I know that I can't take the planet, because attempting to do so breaks the system. Please, can anyone help me resolve this? I just wanna finish playing through the campaign...

I have encountered the same issue with having to re-accomplish the battle for Dathomir, only my game isn't crashing.  I can fight the battle an infinite number of times without taking the planet, forcing me to autoresolve the battle in order to complete the campaign.  This is in both Zsinj-related campaigns.  I did lead the initial assault with Luke Skywalker both times, in case that matters.
