Hugo Version Check

• My Hugo version is within the supported range

Describe the Bug

The site fails to build if two articles have mutually linking article shortcodes.

To Reproduce

1. Create articles A and B
2. In article A, create a shortcode to article B
3. In article B, create a shortcode to article A
4. Try to build the site (live preview)
5. Hugo hangs and stop responding to requests

Expected Behaviour

The expected behaviour would be to have the shortcode working in both articles.
Intuitively, this should be possible given that the "article series" feature already support mutual links.

Hugo Version

Blowfish Version

**How do I get the version number!?**
It should however be v2.98.0 (I believe) as I updated it before trying to build the site via `blowfish-tools`.
