Editions counts are doubled

It appears that the count of copies for each edition on a work's editions page is double what it should be. Here's a simple case:
http://www.librarything.com/work/2328309/editions
Only one person has the book, I only have one copy, but it's showing 2 copies

This has been around a while and mentioned before, though I can't find the reference.

Here's another example:
http://www.librarything.com/work/3566744/editions
All the counts are even, and total to 24, which is exactly double the member count.

I have pointed it out twice. Can't think why this bug is so down the list. Here is my previous post

http://www.librarything.com/topic/96849

It first appeared at the end of May:
http://www.librarything.com/topic/91708 - Tim made a change to the way zero-edition works are counted, which he referred to in message 99 (May 31). The bug is referred to in message 104.

Fixed. It was combining the cached and the "real" (calculated) counts. I may take away the later, since it's rather wasteful of resources to be calculating it every time.

Awesome! Even knowing this bug, it's tricked me time and time again.

Thanks!

Thanks!

I think the edition count doubling bug may be back.

Perhaps as a result of fixing the no copies bug.

So this is definitely back.

Here's some examples:
http://www.librarything.com/work/268283/editions/6494542
http://www.librarything.com/work/1404667/editions/5673559
http://www.librarything.com/work/83166/editions/6463995
http://www.librarything.com/work/2565247/editions/4187293
http://www.librarything.com/work/4615516/editions/5091404
http://www.librarything.com/work/259776/editions/4189406

They all have 8 members, but the editions counts add to 16.

Hope this isn't being missed due to the needs discussion status.

I got it, finally. Basically, for a certain category of books (ones without too many copies), it was calculating the counts twice.
