First i would like to say i am not entirely sure this is where i should place this post mostly due to this actually being one of my first post on a website... ever, but i would like share what i found to fix a bug when trying to install any of the Optional Files.
The bug i faced while trying to install them was each files Description and Image not showing.
To fix this problem i opened up the script for Tale of Two Wastelands - Optional Files in Fomm's Package Manager
Then at Code lines 135 and 136 i changed the following code
pic_Optional.Image = GetImageFromFomod("Optional Files/" + currentOption + "/Image.bmp");
txt_Optional.Lines = GetStringsFromFile("Optional Files/" + currentOption + "/Description.txt");
to
pic_Optional.Image = GetImageFromFomod(currentOption + "/Image.bmp");
txt_Optional.Lines = GetStringsFromFile(currentOption + "/Description.txt");
and every Optional Files description and Image(if they had one that wasn't pure white) showed for me.
I should also mention that i am using Fomm v0.14.11.12
