When I attempted a /60 rangeblock of proxies and unblocked the single IPv6 address, the proxy I attempted to catch in the rangeblock did not get blocked by the rangeblock. This is clearly a MediaWiki problem because a global block using Extension:GlobalBlocking of the exact same range was effective.
