See the attached for the current patch.

When I turn the Scaler gain or offset way up or way down then it acts like I overloaded the SVF. The output from the SVF stops. It does not output sound even after I return the gain and offset to 0.

The only way to get the sound to return is to remove the patch cable and then replace it.

The same thing happened in a delay feedback loop when the amp I was using to control the feedback got too high. Disconnecting the wire and adding it again fixed it, but it seems like once it gets past a certain threshold of feedback, then the pot can't bring it down to a functional level. It just breaks and I hear no sound.

Hmm, yes you can get silly levels that way - signals are clipped on something like +50 dB .. maybe that value should be lower.

Seems to be fixed now, both, by adding some clipping on SVF frequency control and feedback input level.
