Problems with detailed floor slicing

[UDoneMssdUp 0]

I'm using Cura 3.4.1 and am having trouble with the slicing of a miniature I'm trying to print. I posted pictures, one of the solid view of what it's supposed to look like, and one with the layer view. Notice how it's leaving gaps and you can see the supports underneath.

 

I was able to print this before but somewhere along the way in trying to refine the process it's gotten messed up.

 

size is 43x 38y 68z in mm

 

Thanks

The bottom is too thin for the layers to properly slice.

Thank you, I was worried that was the problem.
