Dude, there's no point in using this mod tool in this game because it doesn't work. I have tried to use it in the past and had problems, I sought knowledge and help from the mod developer and he said that the problem is in the game engine, the Attack On Survey Corps developer uses a version of renpy to test, Ren'Py Nightly. These are nightly builds of Ren'Py, created primarily to allow you to help with testing and development of Ren'Py.
Also, the tool's mod discourages the use of nightly builds of Ren'Py to create games, because is instable and also does not offer support for them!
