Something is seriously wrong with the Scriptnode AHDSR envelope
As long as the envelope parameters are not connected to the scriptnode controls up top, everything works fine. However, if they are, after a while (maybe closing the project a few times, I'm not sure, but I experienced this a couple of times already) they get stuck in the middle of a cycle, skip the decay portion or get broken in some bizzare way. Like - I press a key, the envelope CV goes up, but then stops all of the sudden. When I press the key again, it continues from the point that it got stuck onwards, and hangs at some other random point.
Deleting the AHDSR and adding a fresh one solves the problem for a while, but ultimately, at some point, it gets stuck again.
Ok, I figured out what's wrong - samplers inserted into a synth group drone from time to time. When they start droning, the envelope gets stuck.
Actually, no, it just gets stuck after a while when the parameters are linked to scriptnode controls at the top. @Christoph-Hart help!
