Inconsistent results from a mod

[dferstat]

I'm posting this here to Mod Troubleshooting, rather than Technical Support, as I'm having an issue with a particular mod. However, as I've been able to get the mod in question working flawlessly on a different play-through, I'm presuming that the issue is either a mod conflict, or a game bug expressing itself.

I've been using Atlysan's Lynn Pier Parking Settlement quite successfully in a previous play-through. By this I mean that:

1. I can enable Workshop Mode while at the location.

2. Happiness starts at 50%.

3. It shows on the map as a settlement, with population and happiness.

4. It's listed as a workshop on my Pip-Boy/Data/Workshops.

5. I can send settlers to it, and use it as a provisioner destination.

However, on a new play-through, things are different. I first noticed issues when I claimed the settlement, and then tried to base a provisioner there. I found that I couldn't find Lynn Pier as one of the available settlements. I checked my map, and found it visible, with population and happiness. However, I couldn't find it listed on my Pip-Boy as a settlement.

I then loaded a save from immediately before I discovered the location, and tried again. This time, despite claiming the settlement, there are no settlement stats on the map, and it's not listed as a settlement. Two further attempts repeating this procedure gave the same results.

I'd be grateful for any help in diagnosing, and hopefully fixing, this problem.
