Issue explanation

This error seems to happen with HangingEntity-type entities, such as item frames, leads, etc, from structures that generate. Of note is that the structure has to have been made before 1.19, at least, according to the Mojira page.

I feel like this may be causing chunk-related issues, but I'm not entirely certain.

Are you willing to backport fixes to 1.19.2? Namely asking due to the decisions of some mod authors, rendering me stuck and unable to use your stuff.
