Diversified Investments

For some reason, at the moment I did not received credit for Charging Station, even if I contributed.

YOU CAN FORCE THE CHARGING STATION ACHIEVEMENT without having to camp it or to wait the passive respawn!

1. Go to an active Charging Station;
2. Use the Charging Station to charge your cells untill troggs comes to attack you;
3. Use a spell to leave fight like Shadowmeld, Feing Death, Vainsh, etc...;
4. Troggs will start to attack the Charging Station instead of you;
5. Wait untill troggs destroy the charging station, it will reappear very soon after it has been destroyed;
6. Contribute to activate it and take achievement!

I got credit for the charging station by contributing 250 [item=166846] and 1 [item=166970]. I just stood around waiting for it to complete afterwards. For the Reclamation Rig I only contributed 1 [item=166970] and got credit for that.

I think it was buggy before when most of these comments were posted, but Blizzard made some changes. Completing most of these by yourself can be expensive (apart from the Flame Turrets), so it appears that so long as you contribute something and stay around until it's completed you'll get credit towards the achievement.
