What you were expecting to happen, and what actually happened:
I joined a guild to get team player achievement, but it did not trigger. I left guild and joined another one and it still did not trigger.

How often does this happen? When did it begin happening?

I tried twice.

Join guild

Stop guild hopping

How do I get the achievement to trigger?
