Let me see now, you have been using the command allowFleeing.......correct?
EDIT: I got the command wrong, but you know what I mean....I meant allowDammage.
When you release your campaign, if you do that is, everone who does not have version 1.0 will not be able to use that command because it has been removed in later versions.
I don't know about any other older commands that you have used that might have a similar effect.
I'll try to 'think' of a way around it.
