I am getting this error whenever I click the second phase banner, has anyone else got this, and does anyone know how to fix it?

Not sure about the error but you could try clearing your browsers cache or restarting your computer? sounds dumb but might work lol.

Hello everyone!
If you are experiencing issues with the gacha machines, please clear the cache of your browser and reload the page.
Please make sure to clear the first stages of the event's 1st Phase!
Currently, not doing so before switching to Phase 2 will result in an error.

We apologize for the inconvenience,
