Hello,
I have created a blockMesh for a submerged deck within a wave tank, for use with waves2Foam, and it is coming up with an error,

--> FOAM FATAL ERROR:
face 0 in patch 2 does not have neighbour cell face: 4(3 19 23 7)

From function Foam::labelList FoamlyMesh::facePatchFaceCells(const faceList&, const labelListList&, const faceListList&, Foam::label) const
in file meshes/polyMesh/polyMeshFromShapeMesh.C at line 118.

After looking over the blockMesh, it is the "object" that is causing issues. the blockMesh is,

Are you using v1.5? a.k.a. the version before Justin Bieber was born.

could you also please attach the complete blockMesh log file?

You're a fan of the JB too
I am a university student and this is the versions recommended by my lecturer.

no log file is created when running blockMesh in the terminal, but the full message is as follows;
