Hey, engineers! This is the last update for version 21 of the game, unless a critical bug pops up of course.

In this update, I decided to improve the water filtration, since clean water acquisition had been quite difficult, especially in the early stages of the game. Now water is filtered in a primitive construction with a plastic tank, which is crafted from the train construction menu under "miscellaneous". This is the first workstation created in the train construction menu and it is installed on walls.
For filtration, coal, sand, and cloth are still required, but the amount of produced water has been increased.




Before this update, there were 3 locations where the player could not gather sand, limiting water filtration opportunities unless the player stocked up. Sand heaps leftover from construction have been added to 2 of those 3 locations.



Due to frequent complaints about the robot's functions causing the player to get stuck in doorways when attacked by multiple zombies, or the robot deliberately opening player-closed doors to escape from the robot, the robot can now be pushed by the player from any angle, with significantly improved pushback reaction and speed. The robot now also has a function to disable automatic door opening.



Based on player feedback regarding item production times, production times for some items have been balanced and quest item weights reduced, as the previous weight caused difficulty in transporting and completing quests.
