Offboard Artillery in WF PBEM

[berto]

"This was quite a difficult one to pinpoint. Most times there's an artillery unit that won't fire it is a ghost unit, but it seems there's a chance off-board artillery settings can indeed go out of whack, in case there's an original scenario made with an old(er) Scenario Editor, then the same scenario is edited by a new(est?) Scenario Editor."
 
"I can't for a fact say what happened here, ie. what would be the source for this behaviour. Suffice it to say that if (off-board) arty won't fire, first check it is not a ghost unit and secondly if it is an off board unit, remove and deploy again with the latest Scenario Editor."

Would you please post, either here or (better) at the Matrix Forum, the before and after .scn files?  Those would be the best clues to help us pinpoint the nature of the bug.
