So recently my puzzle rating has been swaying between 1710 and 2050 and for some reaon I am getting incredibly hard puzzles that range from 4-7 long, and the moves the bot makes are so weird an unhuman as a response to what I put in, and when I use 1 hint, all of a sudden after I complete the whole puzzle, I lose 16 rating, yes 16, for ONE HINT! Meanwhile back up at 2037 I am getting simple Mate in 1 puzzles that are like 100 rating.
