This is actually to follow up on the problem that was brought up in this thread that has since been Closed:

When I do the same thing that Ogre did in the OP of that post, the website crashes and gives me this error message (hopefully this'll show up properly):

Server Error in '/' Application.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I see the error message when I go to My/Comments.aspx and click on the titles of my storygames from there.

Upon further testing, I've noticed that it's only happening when I click on Warlords: Strategic Conquest and Where in the World is Carmen Sandiego? but not when I click on The Flame (that one works normally). Could it be an issue with special punctuation marks in the title? If it's not that, maybe it's an issue with older stories?

Try clicking on Go Get the Mail! or Surviving Pre-school from your My/Comments.aspx. Maybe the punctuation marks in those titles'll duplicate the error. Otherwise, I have no clue.

From which page? From the My/Comments.aspx page? What the URLs look like when I hover my mouse over the storygame title links?
