A bug has been introduced in v1.2.69 where a collection containing a sound component pointing to a sound that hasn’t been loaded earlier causes the engine to crash when it is created with a collectionfactory.
Example console output:
WARNING:RESOURCE: Unable to create resource: build/default/game/music/act3_1.oggc
