Sprite Atlas not updated

Hi,

I have all sprites in one big png file. This file is automatically split into sprites by custom (editor) script that inherits from AssetPostprocessor and uses text file that described possition.
After adding new images sprites are being drawn with wrong offsets (wrong part of atlas is being used).
It works fine when building locally.

I already tried to turn off library cache and do clean build but it doesn’t help.

ps. I am using latest 4.x
