in reply to Looping through a hash reference is creating a key...?
Thank you all for the responses, just to address a few points brought up..
First and formost, the code above is not representative of the data structure I was using other than in a vague, hash of hashrefs type of way. I do use numbers, but theyre not sorted etc, still need to be in a hash :)
Secondly, with regards to "exists", the problem became apparent because I was attempting to use exists as part of the flow of the code.. briefly:
I hadn't heard of locked hashes, time to do some reading (though they don't look applicable for this particular issue at first glance)

The first loop through the code would work fine, further loops would later would raise warnings (when doing data validation). Once I saw/replicated the problem, it was the lack of warnings on the first loop that raised my eyebrows.$asked = exists($href->{$qid}); if ($asked) { #do stuff } else { #do other stuff } # later %data_structure = ( key => value, key2 => value2, key3 => $href->{$qid}{answer} || 'stuff', #more assignments ); #do things with the data structure
