As I sit here, having 5 starred moving targets with 7:30 on the clock to kill, I find myself needing to waste time to I can actually complete. I figured I would waste it posting this:
"It would be really nice if there was a way to end a completed challenge without having to wait for the clock to run out."
Yeah, yeah, you can do it sometimes like with buying buffs from the kobold in Picture portals. But it would be nice to have some type of option to leave when done on all of them. Ok, back to staring into space (well, randomly killing portrait spawns for the fractional increase in colletables it will net me)
