Well, MMT_Content crashes on editor load, on one of the map objects:
Assertion failed: Pair != nullptr [File:D:\Build\++UE4\Sync\Engine\Source\Runtime\Core\Public\Containers/Map.h] [Line: 495]
Will see what can be done about this.
EDIT: And again debug symbols where not installed and can’t install them because - error: IS-0001 in the launcher…
