I was playing on my survival world and I was peaceful mode, I originally created the world in normal mode, but when I was transporting a villager with a trade of mending, I puted in peaceful mode so no zombie or illagers would attack him, I managed to put him in my base, but I forgot to put back in normal mode, after that I went to the nether to get some quartz ore for a new base and guess what? there were ghasts there, it was only ghasts, there were no zombie pigmans, no magma slimes, no mob, only ghasts, days after the incident, I couldn't access Minecraft pocket edition, it was on the main screen, and the spinning background stoped, the skin couldn't load, I couldn't sign in too xBox account
