No No-AI Spawn

Some mods, like Cyberbricks' Spiders 2.0 (1.12.2 ver1.03) have a bug in it - spawning creatures that have no ai, not responding to attack correctly, and dissappear after re-login.

This mod attempts to fix it, and all similar bugs.

This phenomenon is caused by bad code writing (not checking world.isRemote while spawning entities). If you see a mod doing this, tell the author of that mod to fix it. Before they fix it, use this mod to stop this phenomenon.

Needed client side, not needed server side.

修复无AI生物的bug。有的mod会生成一些没有AI的生物，这些生物重新进游戏后会消失，并且只能被攻击一次。

本mod修复此类bug。
