GZDoom Builder Fucked Up my levels

[GoodChristianDoomer]

Basically the editor got an update and now my levels have nothing in them or all the textures are missing when I play the level. Is there a way to fix this?

Have you included iwad and required texture packs? Maybe you loaded maps with wrong format?

You should have backups of your files normally.

I think it had to do something with that. I fiddled with it and it's fine now
