LogMetaData: Error: MetaData::SetValue called before meta data is completely loaded

Hallo folks,

I beg your help! It’s now 5 solid hours that I’m trying to debug this issue to no avail.

In brief: my project works perfectly in editor. However, when I package, I get this strings of errors – repeated 15 times:

UATHelper: Packaging (Windows (64-bit)):   LogMetaData: Error: MetaData::SetValue called before meta data is completely loaded. /Game/Maps/Laby2.PackageMetaData'
PackagingResults: Error: MetaData::SetValue called before meta data is completely loaded. /Game/Maps/Laby2.PackageMetaData'
 [...]
 UATHelper: Packaging (Windows (64-bit)):   LogInit: Display: LogMetaData: Error: MetaData::SetValue called before meta data is completely loaded. /Game/Maps/Laby2.PackageMetaData'

UATHelper: Packaging (Windows (64-bit)): ERROR: Cook failed.

(I’m attaching the whole Packaging Log just in case you’d find that useful… everything looks good but for these).

I’ve tried a lot of different things trying to get rid of this error, building and rebuilding, taking features out and then back in… and yes, I’ve also uninstalled and reinstalled the whole editor. Nothing seems to work. It really puzzles me, as everything works perfectly in-editor and I do not have any other warning whatsoever.

Thanks in advance if anybody can help! link text

TL DR Solution was to duplicate the original map, update references to point to the duplicate, and erase the original map.

Aaand I managed to solve the issue, although purely through black magic.

I duplicated the map the packaging error was referring to. Rebuild/Recompiled it, and update all references to point to this duplicated map rather than to the original one. Tried to package, noticing that the packaging error was still referring only to the original map. So I just deleted the original map, finally being able to package with no errors.

It’d be lovely to know what did actually happen; anyway I’m happy now things work.
