There were some changes, like the flavor of his favorite smoothies, along with presumably a whole bunch of offscreen continuity shifts that we don't see.
Only a few characters actually noticed, but they thought it was as horrifying as it seems. They decided that the best response was to kill Ben, even though he wasn't the one who destroyed the universe in the first place.
Another group decided to put him on trial over it, for "unauthorized reality warping".
He had to pay a five-dollar fine.
