Achievment "Tough as nail" not working or...?

[LysBlue]

I wanted to be sure if the "mission in town" such as described in the achievment is the one where we help the hospital and found Valya or is it another? (if so wich one?) And I would like to understand exaclty what does it means by "does not raise the alarm". Try to do it full stealth, didn't woked for the SS roadblock at the end of the map. They are programmed to spot any death, even when they are not supposed to see it! Thanks for the precision.

UPDATE: I managed to do it, unfortunatly I won't be able to tell what I've done or not because it was months ago. I'm not even sure if I used or not the chloroform (which was said bugged), or maybe even if there wasn't a time where they were all in search mode (full yellow "!" but I was too far away for them to spot me and so I never had a red "!" and it worked). Sorry if I can't give more details. Nervetheless, thank you everyone for your answers. Hope you managed somehow too!

I managed not to raise alarm (the red "!") but the achievement didn't unlock for me.

This is already the second playthrough I'm doing because of buggy achievements, and it's starting to really annoy me...

How did you managed? Who did you choose on your team? I think it's impossible with sanek in it. I probably should retry with fetisov and Belo

Not working for me either. :( I completed the mission 7 times just to ulock the achivement but without success. Doing the main mission only, no red alerts, only yellow ones when they start searching for you. But that does not count as alarm, right? I am so annoyed as I want a full achivement when I finish the game.

I bet is still bugged and if they are searching it does count as alarm, now if you attract them with whistle or bottles prob not

I never let it get beyond the full yellow and the achievement dropped for me.

If I remember correctly the problem with the road block you mentioned is the Officer (by the fire drum). He can see almost through the house he is facing and through all the bushes on that side. Any kills you make on that side you must move them well away from the scene. Also do not hide anybody of your team in there as he will spot them. The only safe place was the cellar on that side. This took me ages to figure out and I wrongly believed for a while it was because he spotted the guards missing as in other missions this would spook the officer, but on this one it is just that area that is sort of bugged.

I've read in similair topic about chlorophorm bug. You musn't use it :) I'm still fighting with that achivement....
