In this question a user accepted an answer that was later removed by being flagged.
Since the OP doesn't have 10k rep, they can't see the deleted answer, are they able to change the accepted answer or does the deleted answer stay accepted?

If an accepted answer is deleted (which can only happen by flagging or mod intervention), the acceptance vote is typically deleted along with it to allow a new answer to be selected.
Even if the acceptance mark is visible on the deleted answer (which I guess is the case for a flag deletion, given your >10k status and tone of question), remember that the question author doesn't have to manually unaccept an answer in order to accept a new one.
