Thanks for your feedback.

I'll publish an update soon fixing this. That sucks seriously. So tired of those fucking bugs.

If you're interested here is the reason why you have this bug: I wanted to be able to add heroes without updating the app via AppStore. To do that there are datas (like name, description, spells, etc) and images (portrait, talents, etc) SO what I did is, for each image of the app, if it doesn't exist locally the app tries to get it from the internet. But for some reason you have all the required images and still it tries to fetch them like an idiot from the internet.

So on the next update I'll come back to the way it was before and everything will be OK.
