While using automatic rebuild (hugo server, hugo -w), newly added content with a shortcode using .Page.Ressources.Get is rendered incorrectly. On hugo restart everything is rendered correctly:

This issue was also discussed at https://discourse.gohugo.io/t/page-ressources-get-is-nil-on-automatic-rebuild/55737

The issue can be reproduces as follows:

git clone --single-branch -b hugo-forum-topic-55737 https://github.com/jmooring/hugo-testing hugo-forum-topic-55737
cd hugo-forum-topic-55737
hugo server

In another terminal execute:

cd hugo-forum-topic-55737
cp -r content/posts/post-3 content/posts/post-4

Afterwards, the new post is rendered without image under http://localhost:1313/posts/

After restarting hugo the page is rendered correctly.
