Well I'm not exactly sure what could've caused that. I don't remember whether there was a problem or not in the first few hours of the first update's release, that I then (probably) fixed afterwards.
But I am positive that all I changed was the addition of a few bricks, which in no way should be able to affect the other bricks, even if the entire brickpack had changed name, as long as the bricks have the same names (datablock names) and what-not, then they should stay the same.
