Disappearing Deluge

Disappearing Deluge

Hello - I will find my application not working correctly, go into edit, only to find my deluge script on a particular field completely missing.

It seems only to be happening on subforms - and it may have only been happening after I added //comments to my script.  I am going to remove the comments to see if that alleviates the problem.

Has anyone experienced this or know the reason this is happening?
