NRE on hook spamming console

Hey got this spamming my console....:
 

21:06 [Error] Failed to call hook 'OnEntityDeath' on plugin 'CustomItemDrops v1.0.9' (NullReferenceException: Object reference not set to an instance of an object)

can you tell me what was being killed at the time of this error?

Not sure, but it was on a PVE server, it didn't happen on either of my PVP servers.
The players that were on at the time are gone, will see if I can replicate it...

Yeah no luck replicating it yet...
Will keep an eye on it.

I've been trying to replicate this myself on my test server with no luck. If you can catch it let me know and will do what I can to fix it

Changed Status from Pending to Work in Progress

Ok so I was able to catch it, player killed a boar with an LR-300
trying to recreate it myself that said I haven't been able to....
I'm sure it's something to do with it being a PVE server, as I have not seen a single instance on other servers....
NRE missed....

Only happened a couple times.... this time.
honestly weird.

My test server is a PVE and honestly that shouldn't cause any issues with it. I am trying to see if this possibly happens due to an NPC killing something and it not ignoring it like it should. So far haven't been able to get this error myself.

Yeah I don't know what to say...
I haven't been able to replicate it reliably.

I will continue to look into this and hopefully come up with something. If you determine anything let me know. For now will list this as gremlins lol

Changed Status from Work in Progress to Gremlins

Still haven't replicated it but now have seen it happen on my PVP server as well.
so there's that.

Yeah been sitting back watching what is going on when the error comes up and it happened again when a player killed a bear/boar but with an ice ak this time, yeah and a wolf just now too.

Bear, Boar Wolf in that order...

Did the player have permission to earn a drop and if so are they set to default drop chance or VIP drop chance?

Also what are your current settings?

This is my long work week so I'll look into more when I get the chance and hopefully get this resolved 

Changed Status from Gremlins to Work in Progress

I have been trying to get this to happen for me with no luck, it awards an item when killing animals. I even tried with the ICE AK 

I even copied your config to mine and no luck but I notice you have your drop chance and vipchance set to 1 and 3..
"dropchance": 1, "vipdropchance": 3, 

With that you have a 1% chance (1 out of ever 100) for it to even call to drop an item which I didn't notice till I killed like 20 boar and never once got a drop so I had to check lol. But still not getting any errors. 

I have a beta version in our discord that will possible fix this issue now

Thanks for the updates, yeah I know the odds are pretty low, it's done on purpose.
 

Changed Status from Work in Progress to Closed

Changed Fixed In to Next Version
