Slicer errors with large nozzle

[lairdb 3]

I'm getting some weird slicing when using a large nozzle size; irregularities, and in some cases, outright air space.  Nozzle is 1.0; layer height is 0.2.  

 

Attachment slicer1 shows irregularities in Benchy's smokestack.  Slicer2 shows artifacts in the doorway arch; similar artifacts can be found in all the doors and windows.  Slicer3 shows Ben (thing:2795629) with even more artifacts, including a set of layers actually completely missing in the smokestack.
