As for such update as I got busy with work (sorry again).
One of the things I came across in the logs was that on your account you combined multiple rare hats into your collectors barrel hat. A total of around 10 hats were added to the collectors hat, of which in sets of 2, duplicates appear to be added.
By duplicates I mean they share either the same effect or the same prefix, stats, effect, or same prefix, suffix, stats, effect, and paint.
I've created an album from the logs detailing this located here:
http://imgur.com/a/CORrqAs you can see in that album you combined a couple hats, one example shares the same prefix, suffix, stats , effect and paint. This is like having a 5 bags of marbles, each bag is like a different part of that hat. The first being the prefix, second suffix, the stats added by each prefix/suffix, the effect and paint. After drawing each you replace the item drawn into the bag.
Repeating that a second time and getting the same set of objects seems unlikely.
Other times in the logs I saw your account buy 10 money bags of 10 million each, and based on the logs you / your account or whomever was on it, appears to use the bug to duplicate the 10 money bags to 20.
This happens other times too, where way more cash bags than bought were redeemed with what looks like attempts to use the bug appear in the logs.
Edit: If for whatever reason this needs to be unlocked just pm me.
