Vertex out of position in sculpt mode! While I was sculpting a model I noticed a vertex has gone way out of whack and gone inside the model and will not move back to where it should be by using brushes.

It is a vertex generated by the multi-resolution modifier, below is the vertex in question:



Base mesh without modifier:



It did not happen immediately and I am not exactly sure when, it was after 5 or so hours of sculpting I noticed it and it wouldn't have gone unnoticed for a too long. I believe it may have occurred when I was using the Crease brush if this helps.

If anybody knows how to fix this it would be much appreciated, I don't understand how this has happened to one side and not the other also, as it should be mirrored.

Many thanks!
Epiphany hit me and I just deleted the faces over the point in edit mode, switched back to sculpt mode, grabbed the vertex with the "grab brush" and pulled it back to the outside, filled the faces back in in edit mode and then smoothed out the mess that made back in sculpt mode.

Pretty much what Todd suggested!

All good now!
