Checklist

• Via plugins are only running on EITHER the backend servers (e.g. Paper) OR the proxy (e.g. BungeeCord), not on both.
• I have included a ViaVersion dump.
• If applicable, I have included a paste (not a screenshot) of the error.
• I have tried a build from https://ci.viaversion.com/ and the issue still persists.

Please try the latest build(s) from https://ci.viaversion.com/. In case the issue still persists send the new dump

There have been a few client bugs with slime hitboxes in the past, this is likely one of them, in that case there'd be nothing we can do about it
