Does live trading account values drop like the paper account?

Periodically I notice my paper account that I have an algorithm running on drops in value by over 25% without any actual drop in the stock which is weird but it looks like others have this problem too. Question is, is this know to happen for live trading accounts too? Just for an example, yesterday, my paper account said it dropped from $110,000 to 76,000 without any losing positions. Today it shows yesterday the value was 115,000, but again, today’s value is 76,700. Any experience with this?
