Alerts are getting delayed

Alerts from forums that I am subscribed are getting delayed by a day or so!

Does this happen to someone else or just me ?

It's because I just moved the thread from the domain forum into the freebie section 11 minutes ago....

You didn't get the original alert as it wasn't created in the forum you are watching, but I chose to alert you (and everyone else subscribed there) when I moved it to the correct forum.

It's not a bug.
