If i want to update my map how would i do that? theres only the prompt to publish i new one so im confused on what to do
You can hit publish and go through the publishing motions again, this will update your map your able to do little things too like a thumbnail change or redo iARC.
What happens though when you edit your map again after publishing, you need to reupload to private version and do another memory test and get a new map code.
This adds to the list of private versions in the portal and you can select publish on the new map code to update your published map.
So I published my 1v1 map and everything was good, but then when I opened it after I published there were objects that were missing and settings that were resetted , even though in uefn everything is alright , why did that happen ?
