Hi I made a dimension, which has a room in every chunk. Every portal block has an id. It will teleport you to that room which has the same id as the portal. It works with players, but if I teleport a mob, it disappears, becuz its far and the chunk was not loaded. If I go in there first, then the mobs, they will teleport to that far chunk. So is there any method to force load the chunk, so that if an entity travels far it doesnt get removed?

I am assuming you have to send some sort of packet to tell minecraft to keep certain chunks loaded. However i am not sure since i never worked with these type of things before
