I am currently working on an adventure map, and i have only encountered one problem so far, mobs disappear after a short time
Does anyone know how to fix this?

Use the PersistenceMobs filter for MCEdit, found here.

Note that this will only apply to mobs you filter, not ones that spawn afterwards.

You can also edit use nbtedit to edit spawners to prevent any mobs spawned from the spawner to despawn.

In-game nbtedit is way better. When you look at a mob in game, you can type in a command to edit all of its info. There is an invincibility tag that sethbling never took notice of. He uses resistance IV whereas invincibility is much more effective. You can edit literally all of an entitity's information. There is a tag to determine if a mob should despawn too. Research before you post. And actually look at the mod. There is a lot more to it than you have made it seem in your posts here and on another thread on the same topic.

Invincibility is the same but less hacky. Sethbling didn't realize that invincibility was built in. You literally can't hit the mob.

Thank you, I believe that solved the problem
