i have a real solution to the lack of map updates that will require a few hours work once
if no one else can be trusted to create a new campaign file then perhaps @daredevil could create 4 or more of them all with the same name each including all the regular maps and 2 -3 newer ones
then they could be rotated around each week or fortnight or monthly
surely there is someone in your clan that is capable of removing 1 campaign file and replacing with another once per month without breaking the server
this takes a small amount of work once then there can be fresh maps on the server more often
this is required i think because of the campaign nature of jaymod "newer" maps like haunted mansion minas etc. get stale fast and tend to kill the server when overplayed
ive seen the server go from 30+ players to 8 or less when an unpopular map like haunted mansion comes on yet again
