Chart history gap in the H4 timeframe only of GBPAUD with Oanda Demo

 

I have tried a variety of methods to fix this problem. Before, it had been affecting all the lower timeframes as well. A gap from Oct 1 to 16:00 Oct 4. I was able to get the data filled in for the lower timeframes, including the H1, but the H4, no matter what I do, refuses to fill in the gap. Why would only the H4 chart remain broken, when the other ones are fixed?

 
I was getting so desperate that I tried just opening a new MT4 demo account with a different broker. Seems to have fixed things...FOR NOW! DUN DUN DUNNNNNNNNNNNNNNN
 
Oct 3 and 4 are the weekend. Most markets are closed.
 
Markets were running well before 16:00 on Oct 4 on all the other pairs :P Last I checked Oct 4 was a Monday
