The disappearing JD sword? Options

[LZJ]

I have experienced a problem with the JD sword in IA v5 (it disappearing), which I never experienced in v4.2...


SPOILER!

In my vagrant game, I collected all the components for the JD sword in SOA, but I did not forge it then, as I was worried about the difficulty of the battle I would have to face. Hence, I decided to postpone the forging to TOB. This is what occurred:


After facing the battle in the Oasis, I went to the Watcher's Keep to complete the Demogorgon battle, following which I went to the WK outdoors. I Pocket Planed and forged the JD, which told me I had to defeat so-and-so within 7 days, and I Pocket Planed back to WK again. Met the Demon Prince, chose the first dialogue option. Here's where it got strange:

My protaganist was wielding the sword when after a round or so, it disappeared! I have played the game legitimately and without cheating, so this came as a shock to me. Even so, after a few reloaded attempts to prevent the sword disappearing (putting it in my inventory instead of my weapon slot etc), I decided to go through with the battle and see if I could get it back. I didn't, even after wiping out the Demon Prince and his whole bunch of summons (which was rather tough without the sword).

Can anyone help me? I swear I did not cheat, and I installed only the mods in the Readme, with IA last of course.


UPDATE:
The above only happens when I Pocket Plane directly to the battleground. I tried reloading, going to Amkethran first and then forging the JD sword. Went from there to the battleground, and the sword did not disappear. It's a partial relief: found a workaround, but I would have to fight the battle again. Perhaps the above was just some errant bug? I'm not sure now.
