On The Day 2018, Many Glitches Were Reported With The Sans NPC Corrupting And Breaking People's Computer. Some People Reported The Game Not Even Booting Up At All. During Winter, Undertale Would Boot Up For Everyone Who's Had It Installed. It Would Boot Them Up Into Snowdin. No Introduction. No Title Screen. No File Select. Just Snowdin. The Only Character Would Be Sans. An....Odd Version Of Sans. Once They Approached Sans, A Battle Started. The Battle Lasts 10 Hours Before Instantly Killing The Player And Closing The Game. The Update Was Considered Lost Media Until It Would Be Uploaded On A Site Called "UndertaleLostMedia.Com".
