Mixing E10 and 98RON

Sometimes I fill up with E10, sometimes when I am feeling wealthy I put in 98 RON. There was one time when empty I filled up half E10 and half 98 RON. Silly me. Is there any harm in mixing fuel like that?

No, you'll end up with an octane rating somewhere between the two fuels depending on how much of each you used. E10 has an octane rating of at least 94, so the mix will be between 94 and 98.
