That bug was so fun.
This would've been uploaded like monday, but I got struck down by the flu. Headaches all day long with morning classes make for a productive little man. (I'm fine now stop paying attention to this detail)
Oh yeah, a bit of background on this little bug. When the 119th update rolled out, Valve tinkered around a bit with the engie's build code, probably in preparation for the upcoming engie update. This allowed engies to build multiple dispensers and sentries by using 'build 2 x' or 'build 0 x' in the console, where x is any number.
One day later Gaben rolled a patch in, but everyone discovered they could still build stuff by just using negatives for the second number. Woo.
