Still organising heist with two teams (2,3,4,4)
I believe the answer is:
at the same time
'still' is the definition.
(I've seen this before)
'organising heist with two teams' is the wordplay.
'two teams' can mean two replacements for 'team'.
'organising' is an anagram indicator.
'with' says to put letters next to each other.
'team'+'team'='teamteam'
'heist' after 'teamteam' is 'teamteamheist'.
'teamteamheist' with letters rearranged gives 'AT THE SAME TIME'.
(Other definitions for at the same time that I've seen before include "Coincidentally - still - however" , "Notwithstanding" , "27 [AT ONE FELL SWOOP]" , "synchronised" , "nonetheless" .)
