Coil Achievements.. not working?

[GilbertLapine]

So...I've beat through T4 and walked around in T5, but I haven't gotten any of the mapping achievements yet. I'm pretty sure I've seen the whole map for each turn... what gives? Am I just missing some random corners somewhere, or are the achievements not functional yet..?

You'll get the achievement after you killed Twintania. The area behind the hand is huge ;p

[Dano]

there's no map achievement for turn 4, and you only get turn 5 map achievement after you beat it and walked to the end of the bridge

There isn't one for Turn 4. Others are all working, I guess just check your map when are you in there and see if there are any obvious bits missing. I think Turn 2 doesn't give it until you walk down the tunnel to the chests after beating ADS.

And Turn 5 I haven't got either, you need to clear it to get it though.
