"you created a paradox where the original timeline cannot logically exist" Except it CAN exist. The thing about Stable Time Loops is that they're... well, pretty stable. See also: "You already changed the past"
YES ! Finally someone ( or somepony, I'm not sure ) notices this ! The time-travel episode made no sense ! The only reason Twilight became future Twilight was because future Twilight travelled to the past and got her upset, in other words she's the result of something that she's the cause of, it doesn't add up !! And so once again, doctor Whooves has to set out to fix things. Way to go Twi, you got your dimention destroyed. Of all the ponies in town, really...*sigh*
They practically broke this rule in Doctor Who... Well, sort of... With Melody named after herself (You know what I'm talking about if you've watched "Lets Kill Hitler")
