The sequence contains no elements

I have installed latest version 1.8.0 via NuGet and then for Site 1 and Site 2 in a multi-site solution selected a 404-page (child node of the homepage nodes).

The project is running on Umbraco Cloud using v7.5.14

However when I access a page that doesn't exist e.g. mydomain.dk/test it return a ysod
The sequence contains no elements.

Without the package and just configurating umbracoSettings.config it does return the 404-page, but in this case both sites are using same culture, so I don't think Umbraco handle this out-of-the-box.

I have another Umbraco Cloud project also on v7.5.14, where I can configurate the 404-pages from umbracoSettings.config because the three sites are using da-DK, en-US and de-DE.

I noticed it stores id's in the config:

<?xml version="1.0" encoding="utf-8"?>
<notFoundPages>
  <notFoundPage parent="1142">1150</notFoundPage>
  <notFoundPage parent="1143">1208</notFoundPage>
</notFoundPages>

Wouldn't it be better if it stored guids instead, when restoring or deploying content from/to another environment since the ids most likely not is the same, but the guids are.
