I agree it's confusing why the dev would say "there will be", "there is", then "we removed them."
That makes no sense.
Nobody on Steam is complaining about how the game has DRM there so they got ripped off because GOG doesn't (same price & all).
I'd say the bigger issue with the game & the dev's is they say "Iron Harvest is the classic real-time strategy games fans have been waiting for." The idea being CnC/Warcraft era RTS's (as those are the classics). It's not, it's much closer to Empire at War, which is a GOOD game, but a decade past the classic RTS's & a different play style. That's my biggest disappointment I have so far is it's not close enough to those classics.
Don't care about achievements though.
