No, but I haven't used beatslash-lv2, ams-lv2 or deteriorate-lv2 anywhere
else but Ingen.
When the issue happens, all plugins running from these 3 sets are impacted,
but other plugins are still working fine.
That's why I assumed the issue was with my plugins...

I'm not sure I understand exactly what you mean.
Vales changes in the GUI are not received by the DSP, and (if I remember
well) changes on the DSP front (via Ingen internally created GUI) are not
received by the GUI.
The problem is that the issue happens randomly. I spent all afternoon
trying to reproduce it and it never happened. But the days it happens, I'm
always in the mid of something else to do proper testing (creating videos
or actually playing music!)
