Horrible copy and pasted code. Please see https://github.com/tgstation/-tg-station#contributing

and specifically 

>Duplicated code is 99% of the time never allowed. Copying code from one place to another maybe suitable for small short time projects but /tg/station focuses on the long term and thus discourages this. Instead you can use object orientation, or simply placing repeated code in a function, to obey this specification easily.
