Paper: Tab Complete bug

[MatinDark]

Hello, I recently update my paper spigot to latest 1.12.2 version
`[20:04:26 INFO]: This server is running Paper version git-Paper-1561 (MC: 1.12.2) (Implementing API version 1.12.2-R0.1-SNAPSHOT)
but the problem is when I want to do tab complete that was going to send an empty packet to the WaterFall and WaterFall is going to kick me: https://paste.ubuntu.com/p/5fQ7y69D9K/

I don't have this problem on previous build information :
`[20:07:28 INFO]: This server is running Paper version git-Paper-1547 (MC: 1.12.2) (Implementing API version 1.12.2-R0.1-SNAPSHOT)

Plugins, etc?
This is more than likely going to be an issue with a plugin messing with packets, the code isn't designed in a way that we could send an empty packet unintentionally

[MatinDark]

is there any way to send you plugin list in private?

I'd prefer it on the issue tracker as then other people can look into it, given that this issue is more than likely guaranteed to be down to a plugin I'm feeling more inclined to close this issue, if anybody can provide any form of information which indicates that there is a potential for this to occur in our code, feel free to note it

Can confirm this happening after build 1553: https://github.com/PaperMC/Paper/commit/cd5da239f84aa2bb94640bc479b2fb6d8f7ed31d

Can confirm as an issue, but we had it marked down as a plugin thing and I never got around to testing it. Likely candidates are PremiumVanish and ViaVersion.

Edit: Our issue also affected BungeeCord, not just Waterfall.

This appears to be confirmed as fixed, also going to look into dealing with waterfall

Wait, Wrong issue, but 100% guaranteed to be caused by a plugin and not us
