According to the bug fix list the jump to zero issue should have been fixed. Unfortunately I cannot check this because Version 1.70 crashes Cubase (versions 8.5.15, 8.040 and 7.50). The plugin is then placed in the Cubase VST blacklist.
I went back to ver. 1.61 and Cubase excepts this one.

OS: Win7 x64, PC: Intel i7, 12Mb RAM, DAW: Cubase 8.5.15 x64

I did make a screen capture and posted it to my facebook page.
