Pretty sure I've asked about this before, but the slight re-ignition of this thread made me play the game again, which in turn made me want to try hunting down an old version again. Some time at the tail end of 2014 (at least that's when I noticed it), the Fairy Crusher fight was changed to have two fairy crushers from the start, with a third and eventual fourth (sometimes even a fifth) spawning in over time as the first two took damage, while before that update they started with only one, with a second and third being added over time instead. Not only was this way more realistic to beat, it was also actually possible to see the solo animations, which, well... it never really was afterwards. The oldest version I have on my hard drive is from November 2014, and it's unfortunately after this change. No clue if it's the version that came with the change, or just one that came after.
So, the question is this: does anyone know which the last version that didn't have this change was? Unfortunately, most if not all of the old links on his blog are dead, but knowing which version to look for would at least help with the search.
