I can't believe it was such a simple problem hahhah thank you so much!

It hasn't been solved! As noone answered I abandoned the project hahhah, but now that you have the same issue we can maybe get someone to help us!

Has anyone experienced this issue or know what could be wrong?

Here's the repo: https://github.com/PauGuri2002/SovietMod1.15

I've recently made my first mod just as an experiment, to use on a server with some friends. The mod works wonderfully when I test it on IntelliJ and on singleplayer, but when adding it to the server it doesn't let anyone join and shows this error on the client: Internal Exception: io.netty.handler.codec.DecoderException: io.netty.handler,codec.Encoder.Exception: java.io.UTFDataFormatException: malformed input around byte 1 When I used any mod other than mine the error didn't appear. This is the server debug log (it took a while to create a new world cause it's not a very powerful machine, but mods work perfectly on it): https://pastebin.com/Uv43jbXq And here's the client debug log when I joined the server: https://pastebin.com/vkD6grRu Has anyone experienced this issue and could point me to what could be wrong on the mod? Thank you!
