If you fill up your entire inventory with 1 of an item, let's say obsidian, and then do /itemmanager give [player] obsidian, then the plugin will say that the player does not have an available slot even though it could theoretically just stack it on top of the obsidian. This only occurs when the inventory is completely filled and the item you want to give is already in a slot somewhere.
