Try another field, perhaps. The patch today specifically tightened up some validation and could have borked some other part of your arc.
Ghost Busters!
Sounds like one of your clues is the culprit now, instead of the briefing. Take a look at those.
Taking a look at your post. It's pretty obvious what's happening. It's blocking the word naked.
Edit: Stupid me, you said you changed that. Nevermind
I have the same issue with my arc, would love to hear if the OP managed to fix this problem.
I tried to edit my published arc to add some extra advice to the briefing asdn was suddenly told that the line 'I can see sth with my naked eyes' was obscene. Sigh.
So i changed ther line to 'with just my eyes' and republished.
I get a popup ' Unable to publish arc.: The field ClueDescription contains profane or copyright text'
I have tried again mutliple times. I've deleted the entire field, copied to word and rewriytten, the copied back. Nothing.
What a crock. Who do i call?
Eco.
