Entites on a team gets kicked off the team and scores reset when unloaded

I have an entity called "[Quest] Inn Keeper" and it is on the team "quest" with a color of light_purple. When I unload it (TP a couple hundered blocks away) then reload it (TP back.) it is kicked off the team and scoreboards are lost.
Command used to spawn the villager:

/summon Villager 150 95 -177 {Tags:["pathFinder","north","tagDir"],CustomName:"-[Quest]- Inn Keeper",Profession:2,Silent:1,NoAI:1,Team:"quest"}

When I did an entitydata within a radius of 3 right next to it, the console said:

That entity cannot be found
That entity cannot be found
That entity cannot be found
That entity cannot be found
That entity cannot be found
...10 more

And before I summoned the villager there, there were no entities whatsoever!
