Went back and dealt with issue again (9)
I believe the answer is:
retreated
I believe this is a double definition.
'went back' is the first definition.
('retreat' can be a synonym of 'go back')
'dealt with issue again' is the second definition.
(to treat something is to deal with it)
'and' is the link.
(Other definitions for retreated that I've seen before include "Gave up ground" , "Withdrew from enemy forces" , "pulled back" , "given extra medical care?" , "Retired" .)
