How to unbrick you game after any integer gets very high suddenly.
1. Open steam and turn off steam cloud for IdleSkilling.
2. Open your file-explorer and write %appdata% and press enter.
3. Search for the folder Idle-Skilling and delete it.
4. Start IdleSkilling.
Your game should be fixed now and all your progress stays intact.
i am not responsible for any progress lost after doing this, but if its between losing a bit of progress or the game all together, i think this is better. its your choice.
