It happens while spawning some zombie entities on the server.

I tried that the capability was null.

Cause of unexpected exception was java.lang.IllegalStateException: Expecting capability: com/craftingdead/core/world/entity/extension/LivingExtension at com.craftingdead.core.capability.CapabilityUtil.getOrThrow(CapabilityUtil.java:47) ~[crafting-dead-core-1.18.2-1.7.6-alpha(1)(1).jar%2370!/:1.7.6-alpha] {re:classloading} at com.craftingdead.core.world.entity.extension.LivingExtension.getOrThrow(LivingExtension.java:61) ~[crafting-dead-core-1.18.2-1.7.6-alpha(1)(1).jar%2370!/:1.7.6-alpha] {re:mixin,re:classloading} at com.craftingdead.survival.world.entity.monster.AdvancedZombie.m_6518_(AdvancedZombie.java:300) ~[crafting-dead-survival-1.18.2-1.1.9-alpha(2).jar%2371!/:1.1.9-alpha] {re:classloading} at com.craftingdead.survival.world.entity.monster.WeakZombie.m_6518_(WeakZombie.java:51) ~[crafting-dead-survival-1.18.2-1.1.9-alpha(2).jar%2371!/:1.1.9-alpha] {re:classloading} at net.minecraft.world.level.NaturalSpawner.m_47038_(WorldEntitySpawnerMixin.java:186) ~[server-1.18.2-20220404.173914-srg.jar%2382!/:?] {re:mixin,re:classloading,pl:mixin:APP:mixins.arclight.core.json:world.spawner.WorldEntitySpawnerMixin,pl:mixin:A}

Running server: Arclight, Forge: 40.1.59

By the way, in survival, the handleRightClickItem method in CraftingDeadSurvival class, where a null is passed in the performAction/decode method, will cause a crash.

Hello,

Yes, We have had the same issues too. This is due to a later version of arclight.

@Sm0keySa1m0n Can you provide some extra information on this.

I have same issue, it happens more frequently with more players.
Not sure, but my friend seemed to notice when he hears the gun sound (when police zombie spawns), and a few seconds after crashes.

I'm running a plain forge server, nothing more

crash-2022-07-27_21.41.42-server.txt

I'm using spawners to spawn the zombies on buildings, not sure if that would make any difference.

And in the client size sometimes it throws this error out as well :
java.lang.IllegalStateException: no magazine capacity

Does anybody have new info on this, at the moment is infeasible to run a crafting dead server because of this issue.

@PatalJunior Is this still occurring in the latest version of the mod?
