Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

SavePackage error: "Unexpected custom version"


I've just upgraded several projects from 4.18 to 4.21.

In one of the projects, I'm calling UPackage::SavePackage and I'm getting this error:

LogSavePackage: Error: Unexpected custom version "Dev-Editor" found when saving /Game/Maps/BaseLevel. This usually happens when export tagging and final serialization paths differ. Package will not be saved.

I've tried clearing out the cache and intermediate files, re-building, re-saving in editor, but the error is still there.

Could this commit (due for 4.21.2) be related? https://github.com/EpicGames/UnrealEngine/commit/7379c1bee2c043e8873e1e38dc1e347cd3153986

Does anyone have any ideas on what I could try next? Thanks in advance :) Marc

Product Version: UE 4.21
