Watched Threads disappeared ???

I've been collecting threads for future reference by selecting"Watch Thread". Today I wanted to check on one of them and found that my list of "Watched threads" had only one item in it?

Is there some type of rule which would cause the items to fall of the list due to inactivity, age, etc.?

If not, was there a server issue? I suspect the last time I looked at the items on the list may have been much earlier in the year, June or earlier.

Is there any sort of Admin help whereby they could be retrieved from a backup?

My apologies to all for the erroneous prior post due to user error on my part, all of my "Watched Threads" are there. Please ignore or Admin feel free to delete the whole thread.

I navigated to the page by clicking on "Forums:Watched Threads"As it turns out I was seeing only one item which had the title "Unread Watched Threads". "Unread" is clearly in the title but I evidently ignored that. Additionally, under the "Unread Watched Threads" there is the statement: "This is a list of the 20 most recently updated threads with unread replies...". I wasn't focusing on that sentence ending with the phrase "There may be more to view". While that phrase is in the same color as the prior text and doesn't have an underline unless you mouse over it, that phrase is actually a link to: "All Watched Threads" which had everything I thought I had lost.

Again apologies for the error.
