What were you doing when this happened? You seem to have about 20 players on, and the game doesn't like a horse that is 240 blocks up in the world

playing on a server in the spawn i get a blue screen then it crashes

Do you have access to the server logs?

It it appears you cannot load a horse at 18, 240, 91.

i don't know why a horse would be that high up, but your machine doesn't like it.

the server logs might say why you were disconnected and give us the other side of the story.

it dont have access to that but and its only in the spawn area

Is there any way i can fix this?

Is the server hosted on a computer?

It sounds like every time you spawn a horse, the server gets all laggy.

this is only me and the server is cosmicpvp
