buged block glitch in murder

so i was playing murder as ghastly and there was two people left but then they got on the roof of the building by breaking a block and it placing back so then i couldn't kill them and i lost. one of these players was Greendangerpig20. please people of pokefind punish this player some how for he was mocking me about how i could not get him. If you do punish him for this it would make me very happy
