Hi, I've been experiencing an important problem with the Atlas for the last 2 days.
It seems that since my atlas size changed from 1024x512 to 1024x1024, the atlas seems to be losing the references to the proper images. This result with sprites having the wrong icon.
The solution I've found so far is to update all sprites. Luckily, most of the original images are located in the same folder. But this is very frustrating since I have to update all images very often.
