No automatic rebake after splitting topics

When did this fix from 2021 go live?

We are on version 3.1.0.beta5 since July, and there is still weird stuff going on, when we split topics - e.g. Grim Dawn's Loot Filter - #20 by Zantai - Ideas and Feedback - Crate Entertainment Forum

If you expand the first quote in the new topic: Twinking Characters Discussion - #4 by Gnomish_Inquisition - Ideas and Feedback - Crate Entertainment Forum

then you are shown a post in the previous topic, which was made four days later: Grim Dawn's Loot Filter - #22 by Gnomish_Inquisition - Ideas and Feedback - Crate Entertainment Forum

Do we need to update to a newer version, or has the bug come back?

I don’t think updating will help.
This post was one of the posts which were split from Discourse AI - Embeddings - #12. When you expand the quote by jagster, you would expect to see the first post of the topic, because that was quoted. Instead, you see the text of the small action post by @JammyDodger from the other topic.
