XF 1.5 Not All Alerts Showing?

[Matthew H]

This morning I received some feedback from one of my users about a possible issue with the Alerts system. She had 10 alerts waiting for her, all of which were Likes on her last post. When she visited the thread, she also found two quotes, but they weren't on the Alerts list. She checked her alert preferences and they're all checked.

Any idea why the two quotes weren't included in her alerts?

It's possible the quotes were edited in (if memory serves, edits don't trigger quote/tag alerts).
