Map Reseting

Hi. I prepared a campaign with all the maps and the dynamic light, etc. I copied it twice to preapare a few similar campaigns to other people a few moths ago and changed the names. I added more maps in thess new campaigns and edited the dynamics lights. Now Those maps dissapeared in one of those campigns and I only have the original maps and the last 2 maps I edited... What did it happen?

No idea.  Maybe the AWS server shard that hosted that particular game had a problem and ended up being rolled back? Edit:  You might want to fill out a ticket on the Help Center with the game info of the game that lost content to have the tech support people look at the back end of things.  They might be able to track down what happened.  No idea if they will be able to get the other content back though.

Thank you for the advice. As soon as I get how the ticket system works I would do it. I get lost in this page.

It is pretty simple.  The help center is on the Community banner.  Send a request (which has several options when you click on it) is one of the 4 big buttons on the top of the page that takes you to.
