[Mr. Man]

One more thing - the server is suddenly switching campaigns all over the place; I was on a custom map and the server suddenly switched over to Dead Center without warning. Also a big problem with ChrisP's original plugin was the lack of campaign/survival map separation, meaning it's currently unclear if switching from campaign to survival maps what the next set of choices are.

So, the logic overall should be this

For campaigns: on finale map -> initiate map vote for mode -> coop/survival -> voting is in progress -> if nobody votes, the current gamemode stays and forces change to the next mission (defined in ?)
For survival: on round start, continue playing until the max # of times the map can fail as defined in .cfg -> initiate map vote for mode the round before failure -> coop/survival -> voting in progress ->if nobody votes, the current gamemode stays and the current map is restarted.

If you want campaign to flow, you can remove the vote mode and instead vote for a new map.
