At 48:14 on the split timer, it stops counting for some reason. It was my first time using the counter so I don't know what happened. I do show the after credits time in the video and it says 49m 08s. Also at 51:50 in the video, or 46:33 on the split timer, my game unexpectedly alt-tabbed. None of the footage is cut/missing, I just had to tab back into the game and resume playing from there.

MOD note: Please, add one extra split on your livesplit. The game reached the final split that's why it stopped there. Final splitting is happening after shooting Nikolai. I decided to give your run the pass because it's your first run ,so no reason to discourage new runners, but on your future runs do as the above.
