Hello, I am a fairly new server owner, I have an issue right now where certain items, c4, ladders, satchels, that are looted from crates, will disappear when you try and depo them. Say you have 2 C4 in your box, you put a thrid one in but still only have 2 and the 3rd one just vanishes. I dont have a whole lot of plugins but I think BetterLoot or StackSizeController is causing this. Please help me figure this out if you can.  

Are you using the latest  server +oxide
use console command "version"  and "oxide.version" to check
these are the current version today (10/12/2021)

Branch: release

(12:19:29) | Oxide.Rust Version: 2.0.5223

I did both of those commands and everything matches what you posted, I deleted betterloot plugin and it seems to have fixed it but I stil lwant to use BetterLoot, maybe it was a config problem I am not sure.

I also just reinstalled BetterLoot and the problem is back, so it must be some bug within BetterLoot

Big problem you cant add any satchels, C4, or ladders to your chest they just vanish

BetterLoot does not handle transfer between loot container.

The only idea i can think of is that you have set a min of zero for some item in betterloot .  ex.
"explosive.satchel": {
"Max": 1,
"Min": 0
},
Then, BetterLoot can create item with quantity zero and when you merge with other, they disapear.
try resetting the config and datafiles

Ok that fixed the problem thank you, I did not relaize setting values to 0 would do that I thought it invloved the rarity. Much appreciated.
