I could copy mine as well if someone could explain me how to copy a world from xbox to this ticket
So after a bit of testing, the reason for those freezes is indeed a skeleton horse, or something related to it. Thing i've done:
Copied my world so i can turn on creative and cheats without ruining my world
Flew around the map to find something that might freeze the game
Found a Skeleton Horse on top of my base, the game froze when i approached it
Hit it, and after few minutes the hits have been registered and horse died and played thundering sound
After that, the game works fine. Tried to see if it happens again, so i used command "/Summon Skeleton_Horse Minecraft:Set_Trap" and spawn it 60 blocks away from me. Approaching it froze the game again, and yet again the game was working fine after it died
But it only works on this world. Approaching Skeleton Trap on smaller size world correctly spawns 4 Horsemans without problems
Playing on Xbox One X. Some additional info:
It started happening after i turned on Caves and Mountains experimental feature, and had to copy my world to continue playing on it. It was working fine for first hour until i've encoutered a Skeleton horse hundrets blocks away, and after few restarts i've figured out that approaching it was the reason that the game was freezing. After avoiding it and returning to my base i was able to play for 2 days normally before it started happening again, but i couldn't find any particular spot or entity in my base that was causing it
It's set to default, since i am not not using cheats
No. Playing Single Player
I have not experienced that bug again since i've killed that skeleton horse so can't say for sure.
Update 1: Soon in my spare time, I will test it again on creative copy of this world to see if it happens again or not
Update 2: Can confirm that the bug is fixed for me as well. Skeleton horses are no longer freezing my game which was the main trigger for that to happen in my world
