in reply to node with no Vote button (but still vote radio buttons)

That is a bug in the UI which I'm sure I introduced, and relatively recently. Thank you for the report.

FYI, there is no policy against voting on nodes in those old, "closed" sections, nor even on commenting in them. Only new root-level posts have been disabled.

I reckon we are the only monastery ever to have a dungeon stuffed with 16,000 zombies.
