Hello!
Just found out about this mod and I'm having fun playing it! Unfortunately, I encountered a bug in the part where you retrieve gas in a bottle that crashes the game.
The first part goes fine. I talk to the ♥♥♥ with the bottle active, Menderbot shows Niko the controls, ♥♥♥ goes into the airlock. However, inside the chamber, when Niko askes about big cluster of glitched squares, the reply dialog has the portrait replaced by black-and-pink squares, like standart "missing texture" in source engine. The gas collecting goes with no issues. Then, on return to airlock I get following messages:
"An error has occured! ... Missing files! Graphics/Faces/menderbot.png, Graphics/Faces/menderbot3.png"

"Encoding::CombatibilityError : incompatible character encodings: UTF-8 and Windows-1251
- Ruby-files/Handlers/Crash_Handler.rb: 91:in '+'; 91:in 'send_data'; 74:in 'outputMissingFile' (3 strings)
- Ruby-files/Scenes/Scene_Map.rb: 640: in 'transfer_player'; 183: in 'block in update'; 156: in 'loop'; 156: in 'update'; 83: in 'block in main'; 73: 'in 'loop'; 73: in 'main' (7 strings)

- -e:in 'eval' "

"Script 'Ruby-files/Handlers/Crash_Handler.rb' line 91: Encoding::CombatibilityError occured. incompatible encodings: UTF-8 and Windows-1251"

Looking at these, I guess only the first one is the bug itself, the second and third is bug reporting script error? Hope this helps anyway!
BTW, love the window title change ;)
