How to reproduce

Trying to print a simple cross stitch bobbin with a color change near the end (for the color identity number of the thread). When using "No sparse layers (beta)", right after I swap filaments and resume, it prints the prime tower, goes to the part tries to print the numbers and fails because the hot end was turned off.

Actual results

Failed print. Side note: the first time I tried this feature, it printed onto my part (the prime tower was not located anywhere near the part in the slicer).

Expected results

Keep my hot end on? Please?

If I don't use the No Sparse Layers feature, the print resumes fine.
