Checklist

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

I can confirm this bug is present i latest version and wasn't present in build 285 for example.

Players on 1.20.4 are getting kicked. (My server version in purpur 1.21 build 2276)

[kennytv]

Try with the latest releases and make sure you only have Via plugins on the backend, not the proxy as well. Otherwise you most likely have another plugin sending bad packets
