I'm trying to level up my Shaman to level 2 but it's taking ridiculously long. In the meantime I'm left with only being able to kill off lvl 1 ghosts.

The problem is, there aren't ANY! The closest is over 300m.. away. Wtf?  It's been like this over 12 hours and it's starting to piss me off.  Where are all the lvl 1 ghosts?  If I relocate then I don't have any Invaders past level 2 for my Hero to kill.  She's on Level 4 invaders.

What gives?

Why isn't there a better variety of leveled Invaders and ghosts?
