Wrong order at first of rising problem in flock (4,3)

'problem in flock' is the definition.
The definition and answer can be both states of affairs as well as being singular nouns.
Perhaps there's a link between them I don't understand?

'wrong order at first of rising' is the wordplay.
'wrong' becomes 'tort' (legal term).
'at first' indicates taking the first letters.
'rising' says the letters should be written backwards (going up in a down clue).
The initial letter of 'order' is 'o'.
'tort'+'o'+'of'='tortoof'
'tortoof' backwards is 'FOOT-ROT'.
