whenever my alt joins skyblock near my blaze farm (hes in the chest room below) all the blazes disappear that were there....
Are you activating the SPawner above him? Or do u just know they were some left when u were there last?
I believe that it is actually a preventative measure incase a player dies and goes back to their island. So that way they arent attacked again by what killed them.
I was gonna suggest it's probably the chunk resetting cuz of the "new" player to the chunk but this makes more sense lol
so if someone is using the xp grinder and someone else wants to use it then the mobs will all go...doesnt seem like a good feature to me
Well either way there shouldn't be too many mobs built up (against the rules) so it shouldn't affect it too much. And I believe like @Mew said that the chunk the player goes back to if it loaded it the only one it happens to. Chunk that is.
well i get around 100 blaze in a minute because they group together which is part of one of the plugins
