Do you have any inventory based addons installed? If so, check their lua for the code below, it could be an inventory addon adding those 4 entities to your F4 via the “other” category.
go to addons/darkrpmodification/lua/darkrpcustomthings/shipments.lua
Below you’ll see code beginning with
DarkRP.createShipment("". {
model = “”,
entity = “”,
price = ,
amount = ,
seperate = ,
pricesep,
noship = ,
category = “”,
})
So, look for the entities in this lua, you’ll see something like
entities = “storagebox”,
You need to delete these 4 shipments from the shipments lua, save and restart server.
EDIT:
Another thing you could try is going to your
garrysmod/gamemodes/darkrp/gamemode/config/addentities.lua
Now you’re NOT meant to edit this file however, check that lua to see if the storagebox and case are inside there, if they are, just delete them, save and restart.
