x = 0 if x <= 1 then y=1 else y = 0 x+=1 then go back to line 2 and y = 1 is end of the loop i got a log say that y = 1 since the first loop of action and that’s correct… but somehow i also got a log say that y = 0 in the first loop then x = 1 then it go back to check x <= 1 again and end with y = 1 too. it seem like 2 action of if expression happened at once i still have no clue how this happened, maybe due to a bad internet or unusual habbit of clients if anyone know what might cause this, please let me know .. thanks in advance
