Getting hurt randomly on multiplayer

Hello am DreikeRock360 want to talk about on the bug in multiplayer, when I am in the world of my cousin when I walk down the stairs I take damage, I do not know because then when I die appears DreikeRock360 fell from a high place but do not know if it's because I descend the stairs but when I to my world happens so with my cousin and not me and he said that it it does not take damage but he sees I take do not know if only the stone steps because I only use her and this only happens with the guest and the operator of the world does not happen it does not know what it is because the computer does not happen this but hopefully agreeing
