i write today because of the same issue appearing again...
I work now on Live 9.7.5, and i have a roland quad capture (soundcard) with a 256 samples buffer size setting.
i didn't notice this issue until i install again Nerve VST from Xfer.
i'm currently beta-testing the version 10 of Live on my laptop (Xfer's VST isn't install on), i will try tomorrow to see if this issue occurs without the Nerve VST.
I'll keep you updated in the problem still occurs...
In the picture, the MIDI track correspond to kick 2, the audio track correspond to the freeze/flatten version of the kick 2 MIDI track
I used the default preset on kick 2, no modifications.
