Okay so bug started to appear when the nether update came out. before then. "my world" was good in condition. when i was exploring the nether and getting the new nether rite ingot i came across a random structured nether portal. when i finished building it, and teleported to the overworld, i noticed a sunken ship nearby so i found what i could, got a treasure map, and i went to the X spot location. (it was really, really far) i wasted hours to go to the X spot location. when i got close. i noticed that it was near my spawn location. (which i built a house that was in my spawn location) i kinda brushed it off. but later on when i would go and explore from time to time, i notice that every treasure map i find would always go to the same X spot location that is near my spawn point. normally treasure maps will put a X spot location that is NEAR your current location. i was started to get annoyed when this happened. keep in mind this world was created way before the nether update came along. (side note bug yes my health is not regenerating i think it must've glitched when i put it to peaceful in the world options menu.)
