Posts not appearing in communities when other group actors are mentioned.

Tried making a post (link below) to a lemmy community while also mentioning two other groups. My post never appeared in the Lemmy community.
This seems like a bug, when I tried posting to two lemmy communities at once the first went through, the second did not.

Does anyone know what’s up with this?
