Alpinist's notes

Kostya has another riddle to solve. There was a stalker named Alpinist in the Zone, who hid his documents in 5 different stashes in the apartment buildings in Central Pripyat. He wants you to find them.
== Walkthrough ==
The path to all stashes is shown on the video below. Make sure to repeat the exact route, including the tree jump, because it seems you need to touch a restrictor somewhere in between for the first rucksack to spawn. The last stash spawns in either one of two places: either at 2:20 in the video, or at 3:05. 
Alternative, more complex, way. Use it in case the first rucksack above doesn't spawn for you. (the reason for that is unclear)
After taking the last stash, a permanent teleport to access one of the roofs will appear nearby. The location is shown on the video.
