Bug Description

When i join in the server i got the console error which i described above, and also it looks like the placeholders doesnt work because when somebody join the server instead of joined the server it says %player_name% joined the server

Steps to Reproduce

Login with 1.7 client on 1.8 server which is using latest viaversion and viarewind
Got console spam errors

Expected Behavior

Placeholders should work and console errors must not happen

Additional Server Info

This happend into the lobby server which is inside a proxy server ( also this error happens in all other servers inside the proxy )

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.
I have looked at https://www.spigotmc.org/resources/viarewind-legacy-support.52924/ and it does not offer a fix for my problem

Barvalg · Answer 1 · 2023-09-30T08:31:04.000Z

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

c0dingnoobi · Answer 2 · 2023-10-02T16:47:16.000Z

possible that you have any holograms near your spawn location?

c0dingnoobi · Answer 3 · 2023-10-02T16:49:50.000Z

if yes then this pr is the issue which was attempted to fix at bf359bb

just "revert" that pr manually my changing the affected line back to original build it yourself

EURedBoy · Answer 4 · 2023-10-05T20:38:58.000Z

I tried reverting it and use

if (invisible && name != null) {
			currentState = State.HOLOGRAM;
		} else {
			currentState = State.ZOMBIE;
		}
``` but it didn't work, same error same crash

Can you update ViaRewind to the latest snapshot build please?
