Converting replays between 1.26 - 1.28 using a converter app was a 1 second task (not referring to the patch switching tool, which required a lot of effort). Therefore there was an easily accessible replay database built from 2011 to 2018. 1.29 has turned replay files upside down, killing the aforementioned database. Now 1.29.1 killed 1.29 replays. And it's not the end for sure.
