Bonus stash: Yantar

As you travel through Yantar's sewers after escaping the X-16, you hear a weird voice and notice some kind of glowing slime on the wall. 
== Walkthrough ==
This is a an obscure teleport puzzle with audio clues that will lead you to a stash.
Each element of the puzzle will only trigger once, but the rest will stay accessible until picking the final stash up. You have to track the progress through the puzzle yourself. E.g. the typical situation is to trigger the first two messages during your first visit and come later to solve it; in this case you can start from the third clue.
Translation of what voices say:
* 0:10 "Go away, man."
* 0:54 "Go away while you still can."
* 1:08 "Somebody, help!"
* 1:22 "What the hell..."
* 2:24 "Freeze!" (on approaching the stash)
* 2:32 "Well damn... I'm surrounded by idiots!"
* 3:07 "Yuck, that's gross."
* 4:23 "Wake up!"
* 4:38 (Marked One, after looking at the stash again but being teleported away) "Damn... how do I get it?"
* 6:18 "Come on, come closer!"
* (after taking the stash) "You deserved it... asshole."
== Notes ==
* The puzzle is normally only accessible after exiting X-16, but you can also get into the sewers in the reverse direction, from Yantar surface.
* You don't actually have to walk into the fire during the puzzle; the teleport is on the very edge of the flame.
== Bugs ==
* At least one person reported clues failing to trigger when not following the puzzle during the initial visit.
