Lags and glitch

hello mini blocks owner so every single day when we try to play mini blocks every five minutes, there's like this one bug and it keeps happening at our house and everywhere we go me and my siblings like to play mini blocks a lot, but we just do not like this glitch we are hoping that you could fix it. but also there's like this one lag with like the boats like whenever like me and my sister is playing with the boats like one person is moving, but one person is glitched, but they're moving on the other screen and we were hoping that you could fix that too because the boats are like also a lag too because we really we really want to use boats but we can't because the lag.
