Help retrieving a map

Hi, I think I deleted an important file and would appreciate help in replacing it, so as too restore a map. The error could, however, be totally unrelated, so I’ve quoted the dialogue boxes I’ve received and ostensibly relevant sections from the error log.

Dialogue 1 (On Project load)

"Default Property warnings and errors:

Error: CDO Constructor (FP_FirstPersonGameMode): Failed to find

/Game/FirstPersonCPP/Blueprints/FirstPersonCharacter.FirstPersonCharacter_C

Error: CDO Constructor (FP_FirstPersonHUD): Failed to find

/Game/FirstPerson/Textures/FirstPersonCrosshair"

Dialogue 2 (Also on Project load)

“Failed to open map file. This is most likely because the map was saved with a newer version of the engine.”

I know this isn’t the problem; I have tried to launch it both in the version it was made and the newest version of UE4.

If anyone could make sense of this, or recommend a means of recovering the map, I would appreciate the help.

Hi, you could try to recreate these blueprint types in another project (GameMode, HUD…), then copying them into the respective folders. Also, you need to make regular backups to help avoid this kind of scenario.
