kspes: Glad to help :) It's interactions like these that make our games better over time, I love doing stuff like that :)
as for the skirmish, if the saved map is in a state where you already killed all the different types of units or close to doing so, then please send. Otherwise don't waste your time, we'll recreate it while fixing the problem.
PainOfSalvation: Made a save file once i've bought all the units for all 3 races but i didn't save after killing them all, since the achievement didn't unlock.
It's done! :)
We're doing final checks right now and then we'll upload the new version to GOG.
I've checked everything and the achievement now correctly unlocks when you kill ALL unit types of ALL armies, in any number of matches.
If you want to verify how you're doing you can check "achInfo.cfg" file in the userData dir. Once that file contains 27 unique unit names, the achievment should unlock.
You can use this file to cheat, but where's the fun in that :)
PS: I was wrong about this achievement, it used to unlock when you kill all units of ONE army, not all of them, but the problem is that some units just don't spawn often as you mentioned, thus making this achievement very unfair and frustrating.
Thanks again for discussing this problem, I'm sure many players will be thankful for this change :)
I'll let you know here when the new version will be live.
