apon loading a world after adding the entirety of gate of babylons weapons excluding the yoyos and boomerangs, and also adding every tool except the hoe, the game throws an error stating that the string is too long, and crashes.
Encountered an unexpected exception

Fixed by writing the packet byteBuffer in chunks instead a single massive string.
Feel free to reopen the issue, if you face the problem again.

Hello!
