When building scenes, map won't load fully.

I am new to Unity by which I have encountered a problem.
When I'm playing the game in Unity itself, everything is working fine.
The map won't load when in build.
This is in build:

When in unity itself:

The map is made through Tiled. Well, there are errors like when I tried importing the map to unity. Tried re-importing a lot of times but these errors won't go away. I have no idea how to fix them but I thought they are just small errors here and there. By any chance, are the errors behind the reason why the map won't load? These are the errors:

Assets/Tiled2Unity 17-53-57-073 19-27-43-117/Scripts/Editor/ImportTiled2Unity.Prefab.cs(97,13): warning CS0618: 'PrefabUtility.ReplacePrefab(GameObject, Object, ReplacePrefabOptions)' is obsolete: 'Use SaveAsPrefabAsset or SaveAsPrefabAssetAndConnect with a path instead.'

You can however use SaveAsPrefabAsset with an empty GameObject.'
