after me and a few friends killed the ender dragon for the first time in that world we went out put away are stuff and my friends later left the world, i stayed in the world and worked on a few things. My project required endstone so I was going in and out of the end frequently. After a few trips it began spawning me in random places near by such as in a cave nearby the end portal and stronghold or in the village above the portal. This was very annoying and even though I had a bed I had slept in multiple times the in portal room it continued spawning me random places, i restarted my device and other nothing works. Sometimes I spawn in the portal room somtimes the village occainsionally the cave, not sure if it only happens when no one else is in the game but it didnt happen until my friends left.
