Factorio 0.17.74-0.
The option in "Mod Settings" -> "Per Map" -> Factorissimo2 -> "Hide Recursion Technology" isn't working. I've tried turning it on both in-game and in the mod settings menu from the game's main menu. The button works fine, but upon clicking "accept", and going into my tech tree, the technology is still there. Obviously it's not a huge issue; I can simply not research it... but it would be nice not to have it there bugging my OCD. XD
The check box remains checked upon going into the mod settings menu, FYI, it just doesn't do anything.
However, when going out to the game main menu, the checkbox there was not checked, though now that it is, it remains so.
