Payload may not be larger than 32767 bytes

When opening an anti-barrel in the modpack "Modern Skyblock 3 Departed" version "3.5.0" I got the following error (my guess is that there were more unique types (probably with enchantments and such) than expected):

Just came here to add that Project Ozone 3 had to remove the anti-barrel due to it corrupting player data/worlds since it can hold more data then Minecraft has hardcoded as a limit to items or whatever.

Guess there has gotta be a much smaller limit so that it doesn't force a chunk to exceed it's hardcoded data limit. (There was a dupe glitch in vanilla minecraft awhile back where you could overload a chunk with written book data and it wouldn't save. Figure it's something very similar.)
