CK crashes when editing WICourier quest

[ahondara]

Trying to make the Skyrim courier deliver a letter. I've done all my quest stage setup, got the letter made, and gotten to the point where I go to WICourier quest, dialogue views tab, select the dialog about "Got a letter...not sure who from...", and open Topic Info to add a condition to put my letter in his container. I add the condition, click OK, and when I click OK again to leave the WICourier quest box CK crashes. The message reads:

 

"Microsoft visual c++ runtime library, runtime error!" "This application has requested the runtime to terminate it in an unusual way..."

 

Any idea how I can get past this without CK crashing?

 

This letter is connected to a quest for my dungeon mod. I did try to run the mod anyway despite the crash and the courier runs up to me and gives me the letter, and the letter is blank.
