"Failed to find DungeonRoot, NOT generating Dungeon navmesh MissingFieldException: Field 'ProtoBuf.ItemContainer.allowedItem' not found." What is this error and how do I fix it?

Check your Map, is the error from a custom Map or a procedural map?

Procedural

Change the size or seed and report it to FP. Or are you having the same result on every map ?

Possibly simply reinstall the server and then try again!

alright
