NormaExport Error

[zhuhuibeishadiao]

The umap parsing error of scum game (UE4.27.2) is not NormaExport, but I can parse it normally through UAssetAPI
Another project depends on this library. I tested it and found that it was a problem with this library. Or maybe not, I'm not sure.

When I manually removed the "MapProperty" in it and the parsing was normal, I don't know rust programming.
