How to recover lost card activity entries after moving a card to another board?

[Jüri Preobraženski]

I moved a Trello card from one board to another and my notes under "activity" have been lost. The card thumbnail still shows the number of comments/activity entries but when opening the card, the activity entries are lost. 

Is there any way to recover lost data?

@Jüri Preobraženski Are you saying that the actual comments are not showing? I know that the list of activities sometimes changes when moving between boards, but comments should still be there. If you click the show/hide details button to show only comments can you see them there? If you're able to can you share a screenshot?
