The IDE isn't supposed to be able to run with a crash in the code. And if the IDE goes around this crash, knowing its there, it should tell about it. It makes total and complete sense, thinking anything else is f*cked up.
Did you read what i wrote? I dont disagree with you, But making it check for files would make the ide so much slower for big projects,,,Besides, hows the IDE supposed to know that the Gdx.files.anything is an I/O call and that it should check for it? Shouldnt be too hard for ide devs to make , but still, they have their reasons.
I will let expert people to reply now, but i think they wont disagree with what i have said.
