Packet Fixer Mod fixes many common errors related to game data packets and NBTs. This mod is very helpful for players who use large modpacks, as it improves compatibility between different mods. It works by increasing the allowed size for data packets, which helps prevent crashes and data transfer problems.
Features:
- Fixes crashes that happen when an NBT tag is too big.
- Solves errors from badly compressed packets that are larger than the maximum size.
- Stops the game from crashing when trying to send a packet that is too large.
- Prevents chunk packets from using too much memory.
- Fixes issues where data payloads are larger than the allowed size.
- Handles errors caused by VarLong and VarInt values being too big.
- Helps reduce some connection timeout problems.
