Network Exception Caught io.netty.util.IllegalReferenceCountException

[phiwijo]

In some rare cases I get this:

I constantly ping the server every 100 ticks to get approximate ping for a Hud in game, is this an issue in the implementation or on my end?

[hannibal002]

I get the same error multiple times a day and get kicked from the server from it. And I'm only use the ping packet every 10 seconds

[DavidArthurCole]

So this is now happening across SkyHanni, DungeonGuides, and SBA (plus more probably?). Surely this is a bug on Hypixel's end right?

[hannibal002]

Let's see if this simple mixin fixes it for SkyHanni at least.

This should hopefully be resolved in the latest forge mod release - https://modrinth.com/mod/hypixel-mod-api/version/8p64PKBQ

As a side note, I'd recommend not spamming the ping packet. This packet is specifically implemented just for testing the basic idea of the API, and shouldn't be used to continuously poll the server.

@ConnorLinfoot could a new version of the tweaker and Forge Mod API be published to maven please

Oops, forgot to publish the release to the repo, should be good now!

@ConnorLinfoot I believe the mod-api-forge-tweaker package needs to be updated to 1.0.1.2 as well for it to load the new version
