When using a dry_wet container in Scriptnode, the output goes completely silent at 100% Wet if the internal Gain modulation is at its minimum value. This happens because the Gain node is treating "0%" on the knob as "silence" rather than "bypass."! The signal loss occurs specifically when the Gain node is located inside a Chain container alongside an expr node. Even though the Mix is at 100%, if the Gain module within that internal chain is active (on) but at its it mutes the entire output of that general project.
