I encountered a bug that disables the resource and makes it unable to be reenabled until you refresh the project. I stumbled upon this since I use VSCode for scripting, and managing files in there caused it to break for me.
- Create a resource in FxDK (I used lua template for this example)
- Delete a file inside of the resource folder outside of FxDK
- The resource is now disabled, and the only way to reenable it seems to be to refresh the project
