Bug Description

The player was kicked out when switching from server 1.12.2 to server 1.20.2 using the Bunge branch

Steps to Reproduce

1.Install ViaVersion, ViaRewind, and ViaBackwards on the Bungee server
2.Use Bungee to enter sub server 1 normally, then enter sub server 2

Expected Behavior

Normal entry into sub server 2

Additional Server Info

I also use Waterfall with the following plugins: AuthMeBungee-2.2.0-beta1, FallBackServer-3.2.0-Beta1,FastBungeeReport,floodgate-bungee,Geyser-BungeeCord,LiteBans-2.13.3,LuckPerms-5.4.104,MiniMotd,SkinsRestorer-15.0.4,TrChat-2.0.9,ViaBackwards-4.9.2-SNAPSHOT,ViaRewind-3.0.6-SNAPSHOT,ViaVersion-4.9.3-SNAPSHOT

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 the latest build(s) from https://ci.viaversion.com/ and the issue still persists.

If I install Via * on the backend server, this issue will not occur.

This appears to be a private build of waterfall, can you test with #561 of waterfall and see if it persists?
