Subject: Adding a random gate (#41627)
X-Git-Url: https://git.smokeofanarchy.ru/gitweb.cgi?a=commitdiff_plain;h=6fc13a5875ea2cc7d46a4bcbc822cecef0dfd577;p=space-station-14.git

Adding a random gate (#41627)

* Added random gate

* minor edit

* cleaning up my shit after trying to do something faster

* new lines

* some changes

* joke

* UI

* Long Division

* Dont use ctrl + x in 3 am

* I hope these are the final touches

* One thing, I don't know why

* noname commit

* no way, 1kk of code lines edit

* sudo rm -rf ... and something there...

* update

* sometimes its sad
