Iron Farm increase server tps and crash

[AmibeSkyfy16]

lithium-fabric-mc1.18.1-0.7.6.jar and lithium-fabric-mc1.18.1-0.7.7.jar Fabric Loader 0.12.12, minecraft 1.18.1, Java 17

My game crash, tps increase with the time, but i have no more bugs since I moved away from my iron farm. I think that something goes wrong in the code and every time the zombie scares the villagers, the "tps" increases
