"Data pack validation failed!"

Anyone who works on data packs probably knows what I'm talking about... When a data pack is incompatible for one reason or another, it gives a message saying "Data pack validation failed!" and two button options: "Go Back," and "Reset to Default."

This is so unbearable unhelpful. It doesn't tell you what's wrong with the data pack, you just have to look through all your files to try and find it yourself, and it SUCKS! What is the point of telling us it failed if it doesn't give you ANY indication as to what caused it to do that??? Why is there no log telling you what code issue caused it, like it does when the game crashes?

Just make it tell us what file caused the validation failure, for crying out loud!
