Ok, here goes nothing... all 4 lists. Plus some other stuff (keep reading)...

First one note: I sorted the entires in these files. Something I hadn't done in my previous post, but noticed was needed.

You might notice the list for update3 says "bis". That's because I already had a list with update3, but apparently on my last install I only applied update3, since they're meant to be cumulative. But.. there are differences. Here's the file list with just update3 applied (same as my previous post, but sorted):

So... If you only apply update3, you'll be missing:

and also:

(which is not a map)

So far so good.

Next thing I did was compare the CD and Update1 folders. I like to use WinMerge on Windows; it allows to see differences between folders, and it allows to select a list of files that are different and copy the names. Which led me to this:

Or if you want to skip the file, this is the list, one entry per line (just CD vs Update1):

Quite a long list. Again, these are maps present in both the CD and Update1, but they're somehow different (might as well be a single period in one label).

I can't think of a way to compare them except opening them up and... do a visual inspection?

And then repeat for Update1 to Update2; and then Update2 to Update3. Phew.

I think I might need to drop these files into a spreadsheet first. Unless someone beats me to it. ;)

Thanks @thehawk . Thanks to the linked post, I managed to find where the map can be located:

https://www.profantasy.com/library/default.asp

There, you can search for Zhentil and you should be able to download the map. Oddly enough, I could swear that I did have that map at one time (with the ruins and the broken bridge), but I don't recall ever downloading it. Ah, well.

We've been having blackouts (due to storms) lately in the evenings, so I figured I could do the uninstall/install/upgrade thing at work. Turns out, my CD/DVD drive doesn't work here (who knows since when). And we don't have an external DVD drive. And I didn't think about bringing the one I have at home.

I asked a coworker to (network-)share the drive with me, and I did manage to install the base FRIA. However, Update1 asks that I insert my CD into drive F:. My plan was to have the installer do it's thing in the background while I work, but seems like fate has something different in mind. ;) Anyway, this might take me a little longer than expected.

I did manage yesterday to get a list of all maps in update3, and now I have a list of the ones from the CD. Let's see if the forum likes to add TXT attachments:

I'll post the listings for update1 and update2 as soon as I can.

Yes? No? Maybe?

Anyway, the one I was trying to place my finger onto is 5470 zhentil keep. I uploaded a photo of a B/W print later in this same thread. In all fairness, I don't really know if its pre-1368 or post-1368, but the point is that the North bank from River Tesh is shown, as you correctly point out.

But.. it is available in update1. Perhaps that's what you remember when you said:

.. maybe?

Anyway. I currently have update3 installed but I'm tempted to uninstall/reinstall from scratch and see what's what. Perhaps I could add to what @Don V Anderson Jr. is doing.

Oh. All my reports above were with the FRIA viewer. I tried opening 4890 skuld again, but this time with CC3+ and no problems either (Win8 here).

Apparently not.

Seems like my memory played tricks on me. At least for the Zhentil Keep map. I dug up my printout and it seems it's the same map as the one in update3 (with the wards layer hidden):
