Game breaking glitch

[turtwig1123]

I was working on my map in the world editor and I saved it and when I opened the game map two of the levels were missing, I could not access the levels and I could not o past them.
Can somebody tell me what the heck happened.

That happens if you modify a level after starting a save file.

That's common when you edit a world map that has a save file. Start a new save file, cheat if necessary; it's an incomplete project. You could also use illparkwhereiwant in the corrupted save file and walk into the missing levels. You can still enter them although they're not visible. After completing the level it usually becomes visible again and the next path opens normally.
