Strange Error: "#2: requires additional argument"

There's a patch that I've been making that keeps getting this error when I open it up. It's using a VST (Waves Rverb), which I might try to replace with something in gen~, as well as the grainflow package. The error doesn't have an object attached to it. I can't find anything about this error anywhere online, so I'm wondering if anyone may have some ideas of what's causing it or what it means.

make a copy of the patch, start erasing objects till you nail down which one is causing it.
might be waveshell loading into vst
