Error:


There's a simple fix for this!

Go into your Black Ops 3 Directory and enter Radiant > Autosavebackup, there you will find heaps of auto backups of your maps/prefabs.

In your File Browser, Right click > Sort by > Date.

You want to copy the top one of your Map.

Now, go back to your Black Ops 3 Directory and goto Map_source > ZM.

Paste your .map that you copied from your backups and remove the extra stuff at the end so it's back down to zm_usermap.map

Now open your map in Radiant!

If this doesn't work, go back to your backups and get the 2nd top one, keep going down the list until you find one that works.

Moved to tutorial section.

You do know the easiest way to fix that is to open Radiant, Open a file then go to where you're auto saves are: Call of Duty Black Ops 3/Radiant\autosave_backup. Then sort by date and work you're way down till you get one that loads up and it should be 5 mins before you closed Radiant before compiling. Job done.

I know the exact problem and solution to this problem but I'm too lazy to make a post about it. PM and I'll tell you how if these don't work.

Updated.
