Dungeon Architect

Hello.

I just tried to package my game for Win64.
The packaging process went fine, but when I try to start my game I get this:

UE4Editor_DungeonArchitectRuntime!SceneProviderCommand_CloneActor::ExecuteImpl() [d:\build++portal+main+full\sync\localbuilds\plugintemp\hostproject\plugins\dungeonarchitect\source\dungeonarchitectruntime\private\core\sceneproviders\sceneprovidercommand.cpp:180]
UE4Editor_DungeonArchitectRuntime!FDungeonSceneProvider::RunGameThreadCommands() [d:\build++portal+main+full\sync\localbuilds\plugintemp\hostproject\plugins\dungeonarchitect\source\dungeonarchitectruntime\private\core\sceneproviders\dungeonsceneprovider.cpp:90]
UE4Editor_DungeonArchitectRuntime!FDungeonBuilderTask::RunGameThreadCommands() [d:\build++portal+main+full\sync\localbuilds\plugintemp\hostproject\plugins\dungeonarchitect\source\dungeonarchitectruntime\private\core\dungeon.cpp:298]
UE4Editor_DungeonArchitectRuntime!ADungeon::Tick() [d:\build++portal+main+full\sync\localbuilds\plugintemp\hostproject\plugins\dungeonarchitect\source\dungeonarchitectruntime\private\core\dungeon.cpp:122]

Seems like the problem is with the dungeon architect code.
Do I have to do something particular to make this work?
