Unattainable achievements

The 3 hidden achievements of COH2 were only available during the 2015 MWNL event and have not been made available since.

@skillet- I had the same problem, I decided to go get the tanks first on the south side, and worked my way up, where there's a couple of KV-1, and the game went "bugsplat" (pity, I was halfway through that level, want to try it again, but why bother if game's going to crash just because)

[leo_man4u2000]

One achievement that I'm stuck on (thankfully "don't step on the grass" was completed a few days ago.....120 mine field quadrants.....) is Elefant Frenzy. took three of said tanks, blasted through tons of troops and tanks, each one had about 30-40 kills, checked the "leadership" board.....and I was still at 0 tanks out of 5. (the next one I want to do is Katyusha's "missiles everywhere") I even tried Cheevo's tank version, blew away everyone (each tank had double the kills, unless the achievement is tank v tank, not personnel/troops) I know some missions are unattainable, as I played mission 1 several times

[leo_man4u2000]

since replaying this game few months back, I didn't get any mission 1 (listed as M.01 German Engineering) as well as "compassion in war"(rescue civillians) as well as several from other missions (too numerous to count, first five missions from what I counted)

BLITZKRIEG achievement can be finished by using Historical Commanders mod

About the "BLITZKRIEG": The German Mechanized Doctrine is unlocked by default for me so there should be no need for purchase - but I didn't see a "Deploy Mechanized Grenadier Group" for it now?? I have the progress for it, is this ability removed or something??

Too bad the game can't be 100%, wonderful game development being spent on COH3.

[Dragonasuuu]

[Absolute Unit]

[Lord Dindu 69]

Has anybody tried setting system clock to 2015 for the 3 unobtainables ?
Man locking us out of 100 percent for timed event cheevos is dumb :( :(

For Alasborras. No, it cannot the 3 "MWNL" aren´t unachievable even with the steam achievement manager. I´m trying right now to get around 130 of the 452 achievements and I´m around 25% progress. Don´t bother trying to get the 100% is not worth it.
