FabFilter

Hi,
A really strange and annoying feature with the Q4 happened today. In the final stages of a film mix it decided to start to mute audio in (hopefully only) one dialog channel. Bypassing the Q4 back and forth, it resolved the audio for a while, before randomly muting it again. Nothing over fancy eq wise, just normal automation. And no output level automation, all fabfilters are at 0,0 output. Could not find any reason why. Moving the audio to a next identical channel resolved it, but the trust for Q4 is surely gone. The whole session is of coarse full of them Q4`s, being the go-to eq, now a bit of extra tension with the muting audio feature in the final stages. Took a way the dynamic plugin processing in the playback engine, which of coarse would be a nice feature on a full blown session, but the problem was still there. Re-organizing the dialog to avoid (hopefully) the one "dirty" channel was not the highest on the wish list at this stage. Been getting maybe more than usual of the audio processing errors for the Q4 than normally in the session, maybe the dynamic processing is not a fabfilter thing? And that would be nice to get sorted out, fab filters feels like the only plugin getting those.
