Paper/patches/server/0723-Don-t-complete-skull-lookups-on-main-thread-MC-22743.patch
Shane Freeder f18dc1e3c7
Fix NPE when completing skull lookups without a real owner (Fixes #6052)
This looks like mojang introduced an NPE however it was previously being
supressed by the future used by the server, we'll just stick to the legacy
behavior of retainining the existing profile of earlier versions
