Hey and sorry for the late answer@eccol
Hey and welcome on the community forums!To be honest, this is a matter of convention. Some Japanese feel that adding に if there is a comma already is not necessary. Not an error though.
I think that we will change those hints, and simply accept answers with に.

Thanks for the reply!
The sentence I was being marked wrong on was 座ったとたん用事を思い出した。which I now notice doesn’t even have a comma. Is that correct?mrnoone
About 3 years ago
Yes, 座ったとたんに用事を思い出した。is correct , and should be accepted, since it is added to the answer list
It might have been some kind of one-time bug, I will tell the technical part of the team to check it
Sorry fot the inconvenience!
Cheers!
