Hi CuznJay,
Last time I saw this issue it was because the editor could not find the level's editor data (folder). You could check if the following folders exist and are identical save for the Editor/ folder:
- Data/Mods/{YourMod}/Levels/{YourLevel}/
- Data/Editor/Mods/{YourMod}/Levels/{YourLevel}/
If this is not the cause, I would like investigate this issue if you send me the following folders in a pm (in a zip/rar archive):
- Data/Mods/{YourMod}
- Data/Editor/Mods/{YourMod}
- Data/Projects/{YourMod}
- Data/Public/{YourMod}
Thank you so much. I renamed the folder in order to remove the underscores from the name, and somehow it created a duplicate that was missing the terrain folder. Copied it over and now it works!
