Local analysis

Hello, I think I've encountered a bug. http://en.lichess.org/jEwFnsVN/white#21
After move 11. 0-0-0 Whenever I want to use the local analysis, it shows e1c1 (long castle) as the best move, but obviously this move has already been made. And it sticks to e1c1 through-out the whole game, even for black moves!!

It's not a bug. Engine say that black move n10 be7 is bad because than you can castling and make check. In fact you next move was o-o-o, the best move in that moment as suggested by engine.
