I had more then a minute on my clock, I played be7, then time run out, bishop jumps back to c5 and i lost this game. What can cause that?

More likely it was a quick lichess glitch. Next time it happens, try refreshing the page.
I have 45 msec ping with 2 msec server response time, and i have really good connection all the time, so I doubt that it is connection lag.. also I was able to chat with my opponent during those 133 sec till game ended.
