In the context of the post:

Dimensional reduction of Rozansky-Witten theory

I had commented on this question of mine, and there were some responses in the comments section as well, with some useful information I wanted to refer to later. Now all the comments are gone, and I cannot even remember the username of the person who commented. I do not understand why it was deleted so fast when the question is not even a week old.

Is there a way to reinstate these comments?
