This mod raises packet size from 2MB to the java integer limit, allowing certain large datapacks to operate normally and prevent the clients from getting kicked due to maximum packet size, I recommend it for modpacks with Origins installed, as those datapacks tend to send incredibly large packets.
This fixes this bug: The bug in question., which often has messages such as:
- Payload may not be larger than 1048576 bytes
- Payload may not be larger than 32767 bytes
If you are looking for a solution for modded packets past 1.20.2, I recommend using Robin's Unlimited Packets instead.
