Robot boosters lost

The bot resets every 2 weeks. It reset 2 days ago. I can now use the bot on previous levels and rebuild it. Some other players have reported being able to use it for completed levels. Hopefully you can too and build it back up fast. I'm not sure what you mean by having to replay a level.

@Annie1980 I am not sure how you lost your hammers, but here's a post that can help you. https://community.king.com/en/candy-crush-saga/discussion/252961/safeguarding-your-collected-boosters/p1?new=1
