You know how when you place a district, the UI will suggest the best location based on FIMS output? Well... after I made a mod that changes the FIMS output of a district, the preview when placing the district isn't accurate. What's interesting is that it doesn't display the original values (which makes me think it's not hard-coded), but the preview just doesn't include anything that I added.

I just realized as I was typing this that it's possible that the preview only has access to the original libraries/collections. hmmm... I guess I can test that but in the meantime if anyone has any input on this that'd be appreciated :)

I'm doing a few weird things... so the wall is a definite possibility :)

Here are the screens (I circled areas I changed and potentially problematic spots)

Was modifying the harbor, trying to give it land-based bonuses instead of sea, so I created a new effect. Also created a new exploitation rule.

The new exploitation rule. I wonder if I need to specify constraints of some kind instead of "none"?

The new effect - I circled the most weird thing I did, which was using the "invert" tool. I didn't see that being used elsewhere so I didn't have an example case. It was kind of neat that it worked.

The description of the district in-game. Obvious localization issue but seems to match up to the effect

pre-construct - note that both of the original harbor effects from the live game are still functional. It detects the +3 for being next to a market and the -10 for being a new district, but it doesn't show any of the newly created effect.

post-construct - numbers mostly add up correctly
4 non-coast neighbor exploitations + 1 farm district + self = 16 + 3 + 1 = 20 food

I'm not sure how to see the game logs... I can take a look at that if that'd be helpful, if it's possible from the consumer build

tldr: it looks like the "inverted" button in the effect doesn't seem to work with the evaluations

I tested it step-by-step, starting from a base harbour and added the modifications one by one until I saw anything unexpected. The evaluations worked until I added the inverted coastline effect. What was really strange is there seems to be 3 different systems reading doing an evaluation and two of them were incorrect in different ways. I'll attach those screens, in case they're helpful, but this seems like a pretty edge-case situation and might not be something worth fixing soon

Oh, the logs didn't show anything notable. Some unrelated spam, but nothing that had any keywords from my mod/effects. Adding "District_Synergy" as the Serializable Category updated the "placement details" screen correctly for most of the effects. Thanks for the tip :) But it doesn't seem like it was the main problem.

In the two screens below, the Harbor Description and the Placement Details screen both seem to have the same interpretation of the effect. Adding District_Synergy seemed to help, giving the inverted effect localized text and adding it to the Placement Details screen, but both seem to ignore the "inverted" modifier completely, reading it as ONLY coastline instead of everything but coastline.

The second interpretation in the circled area in the image below - that ignores the entire effect that has the "inverted" tag completely, but it accurately reads the other stuff in that effect, descriptor.
And this is the final placement - all the FIMS output matches the effect perfectly :)

This is the exact Effect descriptor I was using in case that's useful

I'm trying to even think of an effect in the live game that uses the inverted tag and I can't :) I wonder if whatever feature needed that inversion doesn't need the UI evaluation display. Maybe it was just never added?

man, the formatting in that post is all over the place :)
