Not sure if it is on Ludeon's side or Steam. My first thought is that some self-righteous people are reporting the mod on Steam, and it's just auto-removed b/c a certain number of reports was hit. Honestly not sure how that flagging system works. OP might know more about which party is behind the removal.
Either way taking down the mod, whether it is from Steam or Ludeon, is ridiculous. Especially considering Vanilla mechanics and the general modesty that the mod has. A lot of people used the mod as well, so it wasn't just some niche creation that only a few people found useful. I can also understand the distress of the mod author, because the removal is so arbitrary. I would be upset if Ludeon or Steam decided to remove one of my mod creations from the Steam Workshop, especially if a similar concept was already incorporated into the game.
