There was an issue with the latest patch. Are you still having issues now, after the hotfix?I manage to make it work but is not a solution or a fix.The only way to work and build the decal is to write everything while you create for first time the decal.All info must fill in in the first window.If i create the files and then i make any kind of change or add anything else it doesn't work.So preview photo description and icon need to be ready and select them from the beginning.Is the only way that it works.
Funny thing is that i can not upload.Hahahaha.I have problem as i have with another 2-3 maps and can not upload.My damn luck.
