The Yellow Update does two things:

A. Adds in cool new items
B. Properly localizes all items using the CHL (Community Highlander) fix.

The CHL Fix allows me to display the proper name of Torsos and Legs, instead of the annoying Torso 008, Legs 012 labels used by the base game.

In order to achieve this, the entry of each item's TemplateName had to be changed, to include the words Torso and Legs, respectively. Example:

TemplateName="CNV_Button_Blouse"

became:

TemplateName="CNV_Torso_Button_Blouse"

Likewise,

TemplateName="Hot_Shorts_CNV"

became:

TemplateName="Legs_Hot_Shorts_CNV"

So why does my soldier Susie have invisible torso and legs?
- Because the game is looking for CNV_Button_Blouse, which no longer exists.

But why is the ENTIRE Torso category gone?
- This is what I don't know, but is base game behavior.

So what can I do now?
- This is a little more complex, as different scenarios require different approaches. I'll do my best to explain what can be done for each.


1. I'M NOT IN A CAMPAIGN, AND I DON'T CARE ABOUT THE POOL

- Excellent. This issue ONLY happens to soldiers who were using items from THIS mod, prior to the update. A fresh new campaign will work properly, with no issues.

2. I'M NOT IN A CAMPAIGN, BUT MY POOL MEANS EVERYTHING TO ME

- Go into the Pool, select Susie. While having invisible parts, you SHOULD still be able to access the category. Go into it, and select a vanilla item. Exit the category (no need to exit back to the character or even back to main menu, it should be enough). Go back into the same category. All items should now have refreshed and should appear normally, and properly labeled. Select the one you want, and boom, you're done.

You should only need to do this once, as the game will now know that Susie is no longer using CNV_Button_Blouse, she is now using CNV_Torso_Button_Blouse.

If for some reason, in the Character Pool, you can't access the category, I'm afraid the only way forward is to recreate Susie. Or....

3. THIS CAMPAIGN IS THE ONE, AND WILL DETERMINE THE TYPE OF PERSON I'LL BECOME. I NEED SUSIE WITH ME

- Go into this mod's Config folder, found here:
...Steam Games/steamapps/workshop/content/268500/1586643354/Config

Each release has its own folder, with Legs, Props, & Torso Pack folders inside. You want to open the XComContent.ini file for the item in question. (using our Susie's Button Blouse example, you would open the XComContent.ini file inside ...Config/Initial_Release/Torso_Pack)

Find the item line(s) of the torso Susie was wearing. Revert the change I made above, so that:

TemplateName="CNV_Torso_Button_Blouse"

becomes:

TemplateName="CNV_Button_Blouse"

Save. Fire up game and load your campaign to be in the Avenger (if you're in tactical, finish up and join us in the Avenger).
Susie should be wearing her Button Blouse like before. Go into Customization and change her torso to something else, either a vanilla torso, or another mod's torso. Save. Exit game.

Go back into the XComContent.ini file, and once again, revert the change so that it's up to date. Remember, in the end, we want the line with Torso(or Legs) in it, to take advantage of the CHL fix and have proper localization.

Now back in-game, you should be able to select Susie's Torso category, and all items should appear normally and properly labeled. Give Susie a new top, save, boom, you're done.

Do this for each item that has gone invisible. I realize it's a tedious, annoying process, but it's the only way I've found to salvage your soldiers' looks if you want to press on with your current campaigns. Keep in mind though, this tedious and annoying process will need to be done only once. There will be no further changes being made to this mod.

Finally, apologies to everyone. I intended to give more cool stuff to the community, and it ended up destroying your soldiers. Sorry for the trouble.
