There is a bundle named Run & Jump & Scroll. In this bundle, there is another bundle named Run & Jump. If you delete this bundle, ok button isnt works and you can’t close behavior screen.
Note: maybe the bundle’s name isn’t Run & Jump & Scroll, maybe its another bundle.

i dont really get what youre saying, but i must agree that theres a bug with bundles. if you delete a bundle then create another one, the new bundle doesnt work right.

@Luminous700 yeah sorry for my bad english
