Mass upgrade issue
Someone knows why the "mass upgrade" mod does not work on the latest version 1.2.12, on the 1.1 version of the game, but if you download the previous version 1.2.11, which is absolutely no different in fact, the mod works and the game starts with it. In the history of versions 1.2.12 and 1.2.11, the entire update text is exactly the same.
