Lycoris Recoil Cafe’s X account made a mojibake nonsense comment and linked to the cafe’s website:

When people fixed the mojibake, the tweet reads (translated):

【Notice】
There is a strange phenomenon on the official website of Cafe Lyco Reco.
We would appreciate it if you could wait for a while until it is restored.

Click on the link of the website and you’ll see what it means.
