Cannot invoke "java.lang.Integer.intValue()" because the return value is null

[WilcoM]

As you mentioned in the now closed issue, the new version does no longer throw an error on the server side, and the server boots up successfully! However, when I installed the mod client side and tested if it'd work on the server, I immediately get a Network Protocol Error, with the following log:

---- Minecraft Network Protocol Error Report ----
// It's the tubes, they're clogged!

Description: Packet handling error

Did you modify the config with your emotes or just put it on a server and call it a day?

In the first case, it's my bad I should clearly say that you have some work to do before hand.

In the second, could you give me your config file?

[fantomitechno]

Can I have more informations on your server config? (content of the config file and content of the emotes folder)

I'm sorry, yes, I didn't add an emote to the emotes folder, it's now there, and I no longer get the error mentioned in the title. However I do get the following error, and MC fully crashes when I try typing : in chat.
