Sometimes I get notifications that simply say "also commented on (random time) ago" with no username or link to click. It's happened on several occasions.

I get this message as well, I've been wondering about it.

This means a moderator has deleted the comment.

Oh, okay. Thanks Carrie!

oh, thanks for the info. I found it really strange but that makes a lot of sense.

It is a bug alright. It will be fixed in the next site version - which I am currently working on. Thanks for pointing this out, I'll keep an eye open so it don't happen again :P
