I found this in the latest snapshot (31/1/24)
Summary:
When you are in low tick rate, the game lets you (with commands) put high level potions (+128), when you switch back to normal tick rate, the game crashes.
Steps to Reproduce:
1. Put your tick rate at 5
2. Give with commands a 128 level potion
3. Put your tick rate at 20
Then the game should crash
