**BUG**
Concise problem statement:
WaveForm plots that are nice and smooth when ploted directly from a sim are distorted/quantised after being saved and then reopened
Steps to reproduce bug:
1. Run sim
2. Observe WavForm plots

3. Save WaveForm file then reopen it.
4. Observe distorted waveforms:

Results: reopened WaveForm plots are distorted (see image above).
Expected results: reopened WaveForm plots should be identical to original plots (see image above).
**Note that this is a relatively recent bug. My earlier WaveForm saves (using version 2x?) were OK.**
