Going into a thread late and seeing deleted comment replying by a bunch of comments. I can kinda guess what the OP said but it would be better if I could see the original comment before deleting.
The possible solution I think is to click the deleted comment like spoiler to view, or add a view button after clicking 3 dots button.
What do you think?
You can go the modlog (small link at the bottom of the page) and search for the username
