This is possibly due to the servers not being shut down after the code expiration, meaning only new servers may not allow players to redeem the code successfully.

The 'SORRYBOUTTHAT' code was added due to some issues with the Hotel+ update, announced in the LSplash Official Discord Server, and was to expire the day after release.

The 'SORRYFORDELAY' code was added due to a reply on the announcement post of the delay of the Hotel+ Update on Twitter.

The 'ONEBILLIONVISITS' code was the first to feature a knobs boost.

The 'SCREECHSUCKS' code could also be found in the description of the decal used for Halt's eyes, Eyes and for the Guiding Light.The 'SCREECHSUCKS' and 'PSST' codes reference Screech and its notorious reputation throughout the community.The '100MVISITS' code was the first code to expire.The 'LOOKBEHINDYOU' code is a reference to a secret on the developer console and a lobby server message.For example, if the player redeems the code 'TEST' but types it as 'test', upon entering the code, the message 'You redeemed the code TEST!' will appear on the screen, even though it was typed as 'test'. Despite this, a redeemed code will appear in capital letters even if it was typed in lowercase letters.The codes aren't case sensitive, meaning any of the letters in them can be typed either uppercase or lowercase.
