When constructing a forum node object and saving it with node_save(), one sees the following notice:
Undefined property: stdClass::$nid File /var/www/modules/forum/forum.module, line 332(file: /var/www/modules/forum/forum.module, line 332)
See #1590008: Notice when saving forum entry → - there are other instances scattered around d.o. The problem is forum_node_presave() assumes $node->nid is set.
I could not reproduce this on D8 (adding the equivalent test code there).

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Forum is approved for removal. See #1898812: [policy] Deprecate forum module for removal in Drupal 11 →
This is now Postponed. The status is set according to two policies. The Remove a core extension and move it to a contributed project → and the Extensions approved for removal → policies.
It will be moved to the contributed extension → once the Drupal 11 branch is open.
