Vase Mode Leaving Voids in ALL Models

[adikted2astro]

So I have been trying to print some vases (in vase mode of course). However, every single model I upload and slice is deformed. The picture will explain the voids I'm seeing. I would say it was the models themselves, but I've checked them and cannot find anything wrong. Not to mention the fact that every one of them has these voids, or errors, or whatever you want to call them. I've tried varying the extrusion width, changing the slicing behavior, even print speeds; nothing works. I have actually uploaded and sliced this STL file in Cura and it slices perfectly. BUT I HATE CURA and do not want to have to change slicers for one print. I'm hoping someone here has seen this and might know a way to counter it. Any help would be much appreciated.

NOTE: the problem is in the bottom part of the model (wvpic) and is not consistent. Each model has it's own unique deformities; sometime on the bottom, sometimes on the last 20 layers, etc.

Are you currently using the most recent version of Simplify3D(4.1.2)? There were some issues in previous versions with vase mode that manifested similarly to this so I just want to make sure.
