I have no idea how to translate いって来た in this sentence. I'm assuming it
doesn't literally mean "go and come back".

Also, have I correctly translated どうしたことか as "somehow", i.e. not the expected
result?

Meaning of いって来た in this sentence
Edited (again -_-)

In this case うまくいって来た means their relationship " **had been going well** "
with their arrangement, so to speak, of one calming the other down, but
something has happened and they are arguing now. Or you could say " **they had
been getting along**."  
Whether "somehow" is a good translation or not could depend on taste, but I do
think it works the way you worded it. Another possibility might be " **but
something happened and ...** "
