charts break down

Hi,

noticed yesterday and today that at some point in time charts just stop updating..bid price line goes up and down..but candle which represents last bar is not present...just blank space...then after some time it becomes visible again...but with not accurate data..for example on EURUSD 30m candlestick chart High is at 1.0071 and Low is 1.09952, but market was above 1.1013..on other platforms and even on cTrader just before candle dissapeared
