So I've been working on my first map for about 4 days now. Just finished the starting area and I was very proud of how it turned out. Made a few additional areas and had the layout pretty much finished. I compiled it, tested a few things in-game, then closed out WaW. Usually if I spend too much time in-game Radiant will stop responding (I'm stuck on an older laptop, Radiant works fine other than that but WaW is very laggy) so I forced closed it like I usually do. Now since I compiled and played in-game I knew I saved it. I then re-opened Radiant and loaded my map, to a blank slate. Everything I've done the last 4 days is gone... I'd normally say whatever and restart but I've been working on this at least 10 hours a day. I am utterly distract... Somebody please tell me this is a common bug with an easy fix.

I can't figure out how to edit but here's some new info.

When I go to load in Radiant, it doesn't bring up the map name on the top bar but it will for other maps. It's like it's refusing to load my damned map.

Whenever I went to compile it, it got stuck at, "Building light transport for everything..." and gave me Error -1073741819

Aaaaand it just did it to another map that I've been working on ever since. Help?

Backup your map_source folder before trying to open your map again.

How many mb is your .map?
If its anything other than 0kb you can get it back.

They're 400ish and 170ish each. I backed it up and loaded it from there and still nothing.

Paste 10 lines from the very top of your broken map here
Or
Open your broken.map and a working.map in notepad++.
Compare the worldspawn settings.
Copy working worldspawn setting into broken map. Try to load your map.

If that doesn't work send me your broken.map through pm and ill fix it and send you instructions how to do it.

I have no idea what happened but there were absolutely no worldspawn settings on either map. I put them in and they work now! Thank you so much you made my day!
