Major issue with a map

Development Getting Started & Setup
, , , ,

So, back in November I started on a map that I worked around 8-9 hours on, then at around 2am in the morning I did something, still don’t know what but the editor crashed, deleting all of my placed assets. I panicked and was never able to restore it. I knew it had saved at one point never got any help finding where that was.

as of right now I have just found a UMAP file made on 11/22 11:17 (the day I lost my map)
I’m hoping this might be it, if it IS, I don’t know how to open it safely.

C:\Users(me)\AppData\Local\UnrealEditorFortnite\Saved\Autosaves(mymap)
this is where it is located ^

Basically you drag it ( in Windows ) to the place where your corrupted map is. Then try open the map from the editor.

Keep a copy of the other map, rather than overwriting it.

Still unable to find a way to safely open the map, I know now that it crashed around 2:37 am because there’s a crashlog file listed there. The file is only like 55kb so I’m very doubtful that is the map. I percisely remember saving minutes before and it is made at 2:35 so if you have any inclination to think it is please let me know!

also since it is a .umap file will it even contained placed assets?

^ done more look into it, found in the autosaves that lists the numbers 0-9, then the letters A-F aplhebetically. Under each one of those integers anohter 2 character folder is present with random asset names. What is this?
(_auto#.uasset)

Each uasset is a map actor, the folders are the way UEFN stores all these

I have no experience with using autosaves

As per ClockworkOcean’s suggestion

Go to User/Documents/Fortnite Projects

Copy your maps folder somewhere for backup and copy the Autosave content somewhere else to back that up too.

probably locate the umap file in User/Documents/Fortnite Projects/Yourmap/Plugins/Yourmap/Content

you could replace it, but without all the other content it may not work if it is dependant on certain uassets…

All the uassets, are located in the either the ExternalActors or the ExternalObjects folder in this directory,

I would be inclined though to first open the latest snapshot map as usual from the editor
You will be able to copy the uassets in bulk from windows explorer and paste them into your map or its Content Browser

Make another snapshot with URC, then close UEFN and replace the umap file, see if it opens in editor
