Errors when exiting the editor when the StartEquipUnequip task is completed

[PabloEsko]

When I exit Play mode, if I have a StartEquipUnequip task in the behavior tree, then 2 errors appear in the logs and the Category ID is missing in the task itself, instead of Equippable -> NULL

Can you post the stack trace in text? It's hard to see from your video.

And I want to add that after errors, you can’t select Category in Category ID, it’s always Null, only restarting Unity helps

An Inventory component is required for an ItemSetManager.

Thanks, I see what's happening. On line 93 of the ItemSetManagerBase change:

m_Inventory = m_GameObject.GetCachedComponent<InventoryBase>();

to:

            if (Application.isPlaying) {
                m_Inventory = m_GameObject.GetCachedComponent<InventoryBase>();
            } else {
                m_Inventory = m_GameObject.GetComponent<InventoryBase>();
            }
