Unable to Load Saved Game in Malachor V [spolier]

[BlackVegetable 0]

After reaching Malachor V and getting to the point where Atton is about to have a showdown with "sleeps with vibroblades", I saved my game.  I am now unable to load that game.  It reaches about 30% progress and then hangs there, not loading.

 

1) When did the problem begin to occur?

Once I reached this point in the game.

2) Did you install the latest version of the mod?

1.8.3 so, yes?

3) What version of the game do you have? (Steam, 4CD, KotOR Collection?) What region is the game designed for if it's the 4 CD version?

Steam

4) Did you update your game as required by your game's region?

N/A?

5) Did you install this over the previous version(s), or did you perform a fresh installation as required by the TSLRCM's read-me file?

Fresh install

6) Did you use the TSLPatcher, if provided?

I am unsure what is meant.

7) Were there any errors in the TSLPatcher installation?

Ditto

8) What other mods have you installed? Please give an accurate list and provide links to each of these mods - even if they are found on this site. (We don't actually know them all!.)

None

9) Can you be more specific about the error? At what point did it happen?

I cannot.

10) Have you tried re-downloading the mod?

No

11) Have you tried using a different save game?

Yes, and they work.  However, I worry that if I get to that point again, I'll have the same issue.

12) Have you tried starting a new game?

No, but given that other saves work, I imagine this would work as well.

Where does the auto-save put you?

It puts me in the sequence where everyone's thoughts are directing you to Malachor V.  I can restart it from there, if necessary -- I just didn't want to do this if I was going to have unrecoverable saves again.

Just for the record (sorry if I should't put this here, but I thought it might be of some use) - I had a similar issue with TSLRCM 1.8.2. For some reason the fight didn't trigger properly and instead crashed the game. The problem solved itself, when I loaded a savegame from a point before the party confrontation with Kreia. I mean, of course it didn't magically fix the unloadable save, but new ones were fine.
