ARK 250.2 introduced a change which truncates stacks at their max vanilla size. This forced me to develop a system to preserve the stacksizes somewhere else.

Here is a list important things to make this work properly:

• QuantityTimer in your GameUserSettings.ini should match your autosave interval (the default value is 15 minutes, which matches the default autosave interval)
  
• DisableQuantity must be false (which is the default value)
  
• You need to execute the [tt]cheat ScriptCommand SaveQuantity[/tt] command before shutdown of your server, otherwise you may loose all saved quantities

The system works by collecting the stacksize of all item stacks above their vanilla limit and saves them into an external file, together with a refrence pointing at those stacks. The problem comes with the way item stacks are moved. Everytime a stack leaves an inventory it will be a brand new itemstack. This causes the reference to that stack to become invalid. Thats why saving of the map state and saving of the quantities has to be synchronized.
