The latest patch has made a small change to the XML code used in buff files, renaming “gameplay_effect_modifiers” to “gameplay_effect_modifier” (note the lack of plural). In this small change, buffs that use the old name no longer work.
This means that gameplay modifiers, such as changes to need and skill rates, applied to buffs will no longer work. This includes the vast majority of custom traits.
I have created a special tool that reads .package files and automatically performs a find-and-replace on buff resources. If you are a mod user, you can simply run the program and you’ll be able to use the mods again without redownloading anything (assuming that nothing else broke with the patch). If you are a mod creator, you can run the program and then reupload the package.
You can run the repair tool on multiple .package files at once. I recommend running it on every gameplay mod you have, to ensure that all the effects work properly.
