Equipment Packet Fix
by AndyNoob
Equipment Packet Fix corrects how equipment item stacks are encoded in the server's ClientboundSetEquipmentPacket, which some clients had trouble reading.
What it does
The mod is a server-side Forge fix for 1.20.1 only. Players do not need to install it, since only the server changes how equipment packets are written. The source is released under the MIT License as open source, and the project has a public issue tracker and source repository.
Key features
Equipment packet encoding fix
Corrects the encoding of item stacks sent in equipment packets, so clients receive them in a form they can read.
Iteration safety in tag writing
Converts the compound tag's key set to an array before iterating, which avoids ConcurrentModificationException during writes.
Safeguard for named tags
Adds a check when writing named tags, preventing the EncoderException caused by a NullPointerException.
