Guild Wars 2

anyone else has trouble with getting a achievement in the final hidden room of w1 z2? its the room that is under the tree, its allot harder then in normal play trough. in the end i made it and entered, but out of nowhere you just drop dead i dint even saw any trap and also i didnt got a achievement for that room. now stuck on 5/11 total 4/5 hidden rooms.

anyone has the same problem or a solution for this?

I read in another thread that this room does not count for the achievement on tribulation mode.

That is good to know
