That's the spewage in the console.   Not sure what's going on.  But it wastn' happening before the most recent update.

Got a complaint that "something is ejecting ammo out of guns when stacking."  I assume that's related to this error.

 

Is there a specific item that triggers this error? 

Try unloading All other plugins and just reload stack modifier and see if the error goes away if so then its a 3rd party plugin causing it, and you will need to track down which one & let me know.

 

I am unable to replicate this error so i will need you to track down what game item is causing that error for you on your sever. 

Most likely cause would be a 3rd party plugin creating some kind of custom item and then a player trying to stack it.

I'll try to figure it out.  It's very much a "specific item" because the error isn't repeating (continuously), but it pops up at specific times.  I"ll see if my staff can help me triangulate what item is doing it.  Thank you for responding so quickly, I appreciate it.

I'm always try to get folks as much data as i can, honestly I most often feel like I'm not giving enough iinformation to be helpful.  If that complaint from a pl;ayer  helps, that's fantastic. 

Do you have any plugins that modify weapons? or ammo or weapon attachments? 

lemme look at my plugins real quick and remind myself, be right back

"Better Attachments", "Firearm Modifier".  Seems to be the only ones

looks like better attachments has had no updates ever, in 6 years.  

Staff member made a clip of it happening.

What storage is he trying to move that gun into? 

Is that a 3rd party plugin storage bag on the icon on the right that is white with TIM on it?

 

we have /bank plugin for vip/staff.  

that's actually thet regular backpack, we have a backpack plugin that alters its size

 

Do you have a link for where the plugin can be found? 

It seems to be specific to 3rd party plugin bug. So i need to know which plugin that is

staff member confirms, it doesn't have the problem using stacks in the regular inventory.   It only happens in backpack.

lemme grab a link to it

https://umod.org/plugins/backpacks

copy of the cs file

Backpacks (1).cs

I just tried it with 6 backpack slots on a default config gen using the ui button and i do not get that error. 

Could you discord me your config file you setup for me to test?

Or like can you re-test that with vanilla F1 spawned items and see if the canstack error still happens? 

It could also be a specific container size causing it ?? But idk what container size you have set on the video.

config file attached

 

Backpacks.json

I updated my previous response.

Did you try the trouble shooting steps? 

I've had to leave my house, so i'm not at my computer.  I've left notes for my fellow owner to try this with  default bag sizes for the owners.  That way, it doesn't affect the players, but it will affect him.  It should hoefully be a sufficient test to see if it's bag size related.  If not, we can run it with "generic" bag size for everyone for a short time.  Btu I'll have to warn everyone if we do that, because our players are used to their bag sizes and the stuff in them would get dropped.

 

In this video, the staff member puts a weapon into a standalone wooden box and it unloads it.  No backpack involved.

That is not a bug tho..

that is intended, this is done to prevent ammo duplication on weapons.

 

Also that doesn't cause the stack error you showed me.
