Few days ago i bought thread highlight upgrades for 2 of my posts, links here:

And yesterday when i bumped them up, i noticed the thread highlight is gone. Now, i haven't seen any mention that it's temporary,
and as far as i know all thread upgrades are permanent (except for the auto-bump ones). Is this some sort of a bug or what?
Any help would be appreciated.

The thread highlight is only for 10 days. If you hover on the item it says

"Highlight your thread, not just the title, but the whole row! Lasts 10 days."

Also below that in the item info area it say "Duration: 10 days"
