VXUS completely disconnected from international market performance overnight. What am I missing?

I've started following VXUS closely but overnight last night I witnessed something that makes little or no sense whatsoever. Overnight, most Asian markets were up, especially the Nikkei (+1.9%) which is largely represented in VXUS. The Korean Kospi was also up substantially (+9.6%) after its prior day collapse. All other Asian markets were also in the green. Euro markets were mostly mixed, with the FTSE (-.49%) and DAX (-.78%) and CAC (-.72%) all slightly/moderately down. The $DXY dollar index was up moderately overnight at approximately +.3% at market open. It was essentially an international blend, with Asia entirely positive and Euro moderately negative. Given my understanding of the international weightings in the VXUS, I expected it to be slightly positive but more neutral given the overnight strengthening of the dollar. Instead the bell rang and it was -1.5%. There was no international index that came even close to that far down, even with the strengthening of the $DXY tacked on. Help me understand what on earth is happening here, because from my perspective watching international markets, it is completely disconnected from reality. To summarize: |Index|Change| |:-|:-| |Nikkei|\+1.9%| |Kospi|\+9.6%| |Hang Seng|\+.28%| |Shanghai SSE|\+.64%| |Aussie ASX 200|\+.44%| |Mumbai Sensex|\+1.14%| |UK FTSE|\-.49%| |German DAX|\-.78%| |French CAC|\-.72%| End result at market open: -1.4%. This makes zero sense to me. **UPDATE:** Turns out I completely missed that Nikkei futures started tumbling around 6am, which is when VXUS also began doing the same.
