Dayz PC version 1.21
I have a private server and want to increase the item spawn rate. I tried:

1. Multiply "nominal" and "min" value by 10 times for all items. (type.xml)
2. Set "restock" time to 0 for all item. (type.xml)
3. Clear all server data.
4. Join the server and use admin tool to test. (ESP tool and teleport around)

There is some problems:

• Many items of one type spawned in the same location. Ex: In the police station: there is tens of Scorpion, in every rooms, every floors is all Scorpion. Another police station: tens of Weapon Cleaning Kit. Another police station: full of SSG 82,... I want to increase item spawn rate, mean many items of many types in one place, not spawn all items of one type in the same place. I increased "RespawnTypes", "SpawnInitial", "RespawnLimit" value (globals.xml) then cleared server data but still not work.
• Some items have low priority when increase item spawn rate (although I set "cost" value (type.xml) to 100 for all items). Ex: When I set "nominal" and "min" value to 100 that mean all items will spawn at least 100 but not. In static contaminated areas (Pavlovo Military Base and Rify), There is full of M4A1 or maybe AKM. But in static contaminated areas it should also have ASVAL, VSS, AntiChemInjector,... too (every time I change values, I always clear server data).

How can I resolve these? (Sorry if my English is not good)
