Title: Fix empty.max exception

During neighbor updating, if 2 alert each other during a remove, the
empty TileMultipart is asked for a light val which leads to a crash at
partList.view.map(…).max

This will fix this, but the real question is how to remove an *empty* tile before it is even checked.
