Subaddresses missing

After reopening the wallet you found that some of your generated subaddresses have disappeared.

Possible causes:
- You closed the wallet by pressing the X in the top right corner instead of using the exit command.
- You accidentally pressed ctrl+c which unexpectedly closed the wallet
- Your wallet crashed

Q: I've sent XMR to a subaddress that isn't showing up, will it still arrive in my wallet?
A: Yes. Subaddresses are deterministic based on your primary address. While scanning for outputs your wallet looks ahead a couple hundred subaddresses, so exiting the wallet improperly doesn't result in a loss of funds.

Q: How can I prevent this from happening in the future?
A: Use the save command after generating a subaddress. Use exit to exit the wallet.
