[FR] Loading UMap from old ue4 4.8.3 ver

[MaverXka]

Im trying to open umap from unreal engine 4.8.3 and i got this error:

[ERR] One or more errors occurred. (Invalid FString length '1768714054') at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions)

If it possible add FString support for 4.8.3

I actually have time to look into this, do you have the full files for this? Having just a umap doesn't really help.
