Some pretty major bugs and issues fixed in this patch, I apologize that they even stayed in the game that long

[*](Hopefully) fixed a glitch where your arm would become invisible
[*]Decreased the rate at which batteries drain from your flashlight by 20%
[*]Made it impossible for bleeding wounds to become infected before you reach a certain threshold of bloodloss, but also increased the chance of infection once you pass that threshold
[*]Fixed an issue where you would still die despite returning to the medical center after shutting the power off
[*]The Spider can no longer place traps in several spots that could severely hinder progression such as stairs, pipe-rooms and certain cramped hallways (please keep in mind that if you have saved your game after the spider has placed traps in such spaces, they will still appear there, but they'll dissapear after a while, after which you can save to get rid of them completely)

All of these bugs and whatnot are gross oversights on my end that shouldn't have made it into the final product to begin with, I hope that they didn't hinder your experiences too much.
