Unlocking achievements? (Locomancer; tag each waypoint)

Has anyone unlocked this achievement? I have all the waypoints on one of my characters (domination league), but I don't have the achievement unlocked. It's not like I can tag the waypoints again on this character, so I'm not sure what I have to do?

I can always try on another character, but I'd like to know if others had successfully unlocked this first...

Are you sure you got every WP on each difficulty?

Yes. I don't think posting screencaps will be much help here (unless I'm contacting support?), but I basically stopped at each map watching them blink to make sure they were shining blue back at me. xD

Does this mean you (or anyone else) has the achievement...?

Would still like some help on this...I'd rather not have to run through some of the merciless zones again (they take forever), and my next character isn't nowhere near completing the game.

Can't unlock it either. Probably broken.

I can't find it, but there's a dev post here somewhere saying that this will be fixed in one of the next patches. You'll just have to click on any previously activated waypoint to get the achievement.

Thank you! Good to know it's not just me. Thread link was useful for other achievements as well, although I'm not working on those yet.
