If a resource is not included when deploying, it means that the editor does not know that it is used. This can sometimes happen if the resource is used by a Plugin and the Plugin didn't register the resource correctly.
In such a case the easiest solution is to make another map that is not connected to anything in the game and use the resources for something on that map, no matter what. This will tell the editor that the game needs the resource and force inclusion.
An exception to this is if the resource has a filename that does not conform to networking rules. In that case you have to rename the resource, because it don't work on non-windows deployment anyway.
