BUG Report: Anybody else get this? (Waves H-EQ)

[Olaf]

I've got a very strange problem that's been plaguing one of my projects for a long while now - always in the same project.

Waves H-EQ bands jump randomly either when you press play, or when you move the playhead along the timeline, like in this example.

In this case it happens with 4 instances at once, on repositioning the playhead.

It only happens when there's an undo/redo history in the plugin, and it doesn't happen to all the instances.

Anybody else ever got this?
