A bug has been reported where post reactions are lost when moving a post. Richie initially reported the issue, providing screenshots of the post before and after the move. Lilly was able to reproduce the issue on her dev instance, noting that it only occurs when the post being moved is the topic post (OP).
The repro steps are:
Go to a topic post with existing reactions.
Click the admin wrench and select the post.
Move to an existing topic.
Existing reactions disappear (except for hearts).
Lilly provided additional screenshots to illustrate the issue. davidb confirmed the issue, noting that it seems to be specific to the first post in a topic. The issue has been fixed with commits in core and discourse-reactions.
I can reproduce this as well on my dev instance, but only if the post being moved is a topic post (OP).
Repro:
1: Go to a topic post with existing reactions.
2: click the admin wrench and select the post
3: move to an existing topic
4: existing reactions disappear (except for hearts)
