java entity modle makes my game crash and not work

Okay so basically you can go into the java file of the Model when you export it and When you look inside it, And Since I had this exact same problem there's the line: " public class example<T extends> extends EntityModel<> { ",   

Which it should actually be: 

"public class example<T extends Entity> extends EntityModel<T> {".

And sadly I had to keep writing  Entity and the Letter T every time I wanted to add a model, but today it just fixed itself somehow

and hopefully this should work because I spent like a day and half trying to fix it

This may be the solution, it worked for me:

Make sure you don't have a folder inside a folder in blockbench.

For example, dont have 

Legs(folder)

>Lleg(Folder)

>>Lleg(block)

keep folders seperate
