I've got news on this subject! I sent a twitter to Ed concerning this map...

... and here's what he has to say:

So of course, we now have to keep the map as canon! ;)

Sure.

Though I'm not sure how much level of detail we need for such a guide, but here goes (I just noticed a typo in one of my images above):

Create "10020 Blackfeather Bridge Village.FCW"

1. Make a copy of 10020 Blackfeather Bridge.FCW (from CD or Update1) and name it "10020 Blackfeather Bridge Village.FCW"; then open it for editing.
2. In the lower-left part of the map, just above "Meredith's Way", create a text label saying "To Blackfeather Bridge".
3. Just above the new label, create an arrow pointing to the top-left (northward).
4. Add a new hotspot to "10020 Blackfeather Bridge.FCW" that encompases the created label and arrow.

"10020 Blackfeather Bridge.FCW" (from Update2 or Update3)

1. Near the bottom of the map, create a text label saying "To Blackfeather Bridge village".
2. Just below the new label, create an arrow pointing to the bottom-right (south east).
3. Add a new hotspot to "10020 Blackfeather Bridge Village.FCW" that encompases the created label and arrow.

"Featherdale.FCW"

1. Change text from "Black Feather Bridge" to "Blackfeather Bridge village" (2 entities)
2. Change hotspot from "10020 Blackfeather Bridge.FCW" to "10020 Blackfeather Bridge Village.FCW"
3. Add a new hotspot to "10020 Blackfeather Bridge.FCW" above the bridge, just above the symbol for the village.

Here's an interesting one... 10020 Blackfeather Bridge.FCW

The maps for cd-update1 and update2-3 are completely different. As far as I can tell:

• CD and Up1 show the Blackfeather bridge Village.
• Up2-3 show the bridge itself and surroundings.

My proposal, would be to keep both maps:

1. Rename the one from CD or Up1 to "10020 Blackfeather Bridge Village.FCW".
2. Add a link to this new map from Featherdale.FCW
3. Add a text link between the two 10020 maps.

Thoughts?

So... I took a dive to see which were these missing background images.

As fas as I could recall, FRIA didn't support images at all, and it does seem to be that way. This is the FRIA screenshot with all layers shown:

And this is the same map in CC3+ with all layers shown:

But that's not all. In CC3+ you can go to File->CC2 to CC3 conversion... and choose a target style (I chose dungeon CC3 style) and this is the result:

As you can see, the image is loaded automagically (doesn't look too good, though). What you can't see in a screenshot is that multiple sheets were added (FRIA didn't have sheets either). BTW, just deleting the entity with the missing fill, seems to show the same image than the FRIA.

My guess? This was probably some early experimentation towards adding raster fills to maps, but never made it to the official product. The fact that FRIA simply ignores these entities makes me think this theory could be right.

@Don V Anderson Jr. ,

... like thehawk said, Moonshae Island.fcw and Viledel's Isle.fcw are essentially the same. Just be sure not to confuse Moonshae Island.fcw with Moonshaeslc.FCW, which is the parent map:

As you can see, the parent map points to Viledel's Isle.fcw (so does 0030 Temple of Selune.FCW); which is why I'm suggesting avoiding links to Moonshae Island.fcw.

...

I haven't delved into XPs yet. But this would also be useful. I too have thought it might be useful to create an XP/script that saves all Info->List information to text files (in batch; one txt file per map) so that we can compare changes between different versions of the same file across updates.
