I made a private video showing it, when i add him to the team you can see that his name tag turns red, so that confirms he is in red team.

minecraft 1.8: Mobs don't atack team mates.
minecraft 15w35e: Mobs don't atack team mates.
minecraft 15w36c Mobs atack team mates.
It's a bug.
And i was in creative when i summoned the first skeleton and joined the team, when i turn in to survival he started shooting.
Nope, it dosn't give error, if i list the team players it shows the skeleton id and the testfor @e[team=red_team,type=!Player].
This works in the 1.8 and i remeber that it worked in the 15w35e (I just tested).
i have an idea, they can make that the things you throw to the hopper to the ender chest gets in a invisible inventory and the only way to take them is puting a hopper under a ender chest (the same one or other), so in multiplayer will be a public chest our something like that
Why this report is invalid?
