Bug to Fix: Pricing calculation in Portfolios
There's some sort of calculation error that occurs on portfolios if you leave the page open and return to it within an hour - the values change completely - when you refresh the value returns to normal

You don't have to wait long for this to happen. It occurs regularly within a matter of seconds, but only for the overall portfolio value. In my case, the wrong number looks rather like the correct number (in £ sterling) translated into US dollars, even though the £ symbol (not $ symbol) remains.
