Usernames disappearing

[znepb]

Describe the bug

When using /seen on some users that has not joined in (seemingly?) more than 64 days, the initial seen command will take longer than usual to execute, but then execute successfully. Any further seen commands executed on that user show that the user has never joined. It also seems to wipe any UUID/username cache, affecting claims, and returning their owner values to UUIDs.

To reproduce

1. use seen command on player that has not joined for a while
2. It will take a few seconds to run, but then return successfully
3. Follow this up with repeating the previous command
4. You will see that the user is now reported as having never joined the server.

Expected behavior

notice that the UUIDs are different, for some reason it's caching an offline mode UUID (version 3 instead of version 4)
