This issues is happening constantly in UniversIO modpack. crash-2023-07-24_07.30.52-client.txt

It doesn't happen always, but it surely happen while hovering items without Reactive tags, in a chest. Last time it happened, it was over a Lead (#minecraft:lead).

This issue should only occur when hovering over Litmus Paper items from before the 5c update, and has been fixed as of 5e. Can you reproduce this without Litmus Paper being involved?

(For reference, UniversIO currently uses the version 5d which, frustratingly, still has the crash)
