Hello,

Upon exploring The End. The server stalls with the following stall report created by Sampler:

stall-2023-11-07_19.01.37-6.txt

Disabling the affected mobs allows the players to explore the end without the server "Hanging". Disabling this mod out right and the hangs stop entirely.

Any ideas?

The issue is in B:"Slime blocks bounce off sides"=true in the Quark config, try disabling that!

This issue was driving me crazy, until Handeril in the 1.12.2 Modding Coalition discord helped me narrow it down.

For some reason, this tweak in Quark may be the issue:
https://github.com/VazkiiMods/Quark/blob/1.12/src/main/java/vazkii/quark/tweaks/block/BlockSpringySlime.java

As the stall starts with:
at vazkii.quark.tweaks.feature.SpringySlime.applyCollision(SpringySlime.java:146)
at vazkii.quark.tweaks.feature.SpringySlime.applyForAxis(SpringySlime.java:141)
at vazkii.quark.tweaks.feature.SpringySlime.onEntityCollision(SpringySlime.java:103)
at vazkii.quark.base.asm.ASMHooks.applyCollisionLogic(ASMHooks.java:210)

Which then points to Fish's Undead rising with:
at com.Fishmod.mod_LavaCow.entities.flying.EntityFlyingMob.func_191986_a(EntityFlyingMob.java:293)

The potential conflict is in the AI of EntityFlyingMob, starting at Line 293, which comes before:

this.parentEntity.getMoveHelper().setMoveTo(d0, d1, d2, 1.0D);

in this task:

    {
        Random random = this.parentEntity.getRNG();

        double d0 = this.parentEntity.posX + (double)((random.nextFloat() * 2.0F - 1.0F) * 16.0F);
        double d1 = this.parentEntity.posY + (double)((random.nextFloat() * 2.0F - 1.0F) * 16.0F);
        double d2 = this.parentEntity.posZ + (double)((random.nextFloat() * 2.0F - 1.0F) * 16.0F);
        
        if(this.parentEntity.isWet())
        	d1 = SpawnUtil.getHeight(this.parentEntity).getY() + 3.0D;
        else if(Modconfig.FlyingHeight_limit != 0 && (double)Modconfig.FlyingHeight_limit < d1)
        	d1 = (double)(SpawnUtil.getHeight(this.parentEntity).getY() + Modconfig.FlyingHeight_limit);
        
        this.parentEntity.getMoveHelper().setMoveTo(d0, d1, d2, 1.0D);
    }

The issue is in B:"Slime blocks bounce off sides"=true in the Quark config, try disabling that!

Another solution was to disable Quark compatibility. But I can also try that.

Should be fixed in #162
