Often when I type
@[person] at the start of a comment, the
@[person] disappears without warning when the comment appears, and even when I try to click on the little white box above to auto-select, it won't allow me to do so. Why is this happening? I seem to always be able to @ people as long as it's not the first word of the sentence, but it sometimes fails when I start the sentence with @. Other people seem to be able to do this fine.
Have I been stealth banned from @ing, is this a bug or is there some bizarre and complex reason for it (like with the weirdness that is the 'Curious' badge rules...)?
