That's literally all. ```
Basically, when logging in to a 1.16.5 server with a 1.8.8 client, the game instantly crashes and kicks the player. No errors show in the server itself, and the only error that I could see was in the WaterFall proxy, which is attached above. Connecting on 1.9 works just fine, and connecting with ProtocolSupport also works.
**How can we reproduce it?**
Steps to reproduce the behavior:
1. Install ViaVersion, Backwards, And Rewind on a 1.16.5 Paper server.
2. Connect to the server using a legacy version (1.8)
3. ???
4. Player crashes and sends an error in the bungeecord.
I can't exactly give good steps, since I'm not too sure what's causing it myself.


**Expected behaviour**
The legacy players should be able to connect to the server without crashing.
