Description of the bug

I painted a model, enabled wipe into infill. Then to try to reduce purge tower, I created an additional instance. The wipe tower didn't change. I went to look at the infill and the 2nd instance of the model was missing most of it's infill.

Project file & How to reproduce

N64.zip

1. Open the project

2. Slice it and check for infill (it should be there)

3. Select the N and click + on the keyboard or the options bar above

4. Move the new instance to a different location and slice.

5. The infill of the 2nd instance should be mostly missing.
