(In fact, something like that is arguably necessary in order for there to be "timecops" or any other way of knowing the history you're in isn't the correct one; otherwise, even the timecops' memories and records would be changed.)
Continuum has something like that in the frag system where everyone who is affected by a paradox takes frag and goes insane as time is pulling them to fix it. This allows the player characters a way to weaken other narcissists (enemy time travellers) with minor edits without making every single spanner (time traveller) mad at you, just remember to fix the paradox once you've bagged the narcissist.

This also allows for interesting stacking of fragging yourself so you can frag yourself safely by blocking an unfixable frag, while editing your memories so that you think the unfixable frag happened when you went back to watch it.
