Seems easy enough eh? I would think that getting that in under 5 seconds would be harder than 2048 in a few minutes!
They were removed because they were trivial, especially with the NKRO exploit which let you get these tiles in fractions of a second. I wouldnt mind a cat extension for them however a user had a particularly laggy computer, that when coupled with NKRO lagged the timer in some way and caused it to think that he achieved impossible times, and as lag varies from computer to computer the categories were removed. I myself had a similar issue actually, where I would get 3 or 4 tiles which the game said I got at the exact same instant, however the footage shows that the start of each of these runs corresponded to a lag spike.
I'm the one with the terrible pc, I used lag abuse to get some times when I stumbled upon it and it happened to show more why small tile categories are not a great idea. Before that though I got the 256 tile in under 4 seconds long before I got an ok 2048 time
