Neruina Mod (26.1.2, 1.20.1) – Ticking Entity Fixer

Neruina Mod can help you in situations where a block, mob, item, or even player causes a crash (game crash). This mod tries to track the problem that will cause the crash and attempts to keep the game running with minimal impact. If it’s a mob, it will kill it, dropping loot and inventory. If the cause is a block, the mod will limit it, but its inventory will remain accessible to you. If the cause is an item, the item will stop functioning but will remain in the game and can be used in crafting. If the cause is a player, the player will be kicked immediately.
