***You can detect RemoveAllItems calls by making sure that the player always has a weightless non-playable item on their person, and using an inventory event filter to listen for that item's removal. Under that circumstance, only a removal of all items will ever cause your OnItemRemoved handler to fire. | ***You can detect RemoveAllItems calls by making sure that the player always has a weightless non-playable item on their person, and using an inventory event filter to listen for that item's removal.

* If player uses a poison to apply it to a weapon the event is fired twice: before and after the confirmation dialogue. If canceled in the confirmation dialogue then is not fired twice. | * If player uses a poison to apply it to a weapon the event is fired twice: before and after the confirmation dialogue.

*If you need to temporarily stop OnItemAdded and OnItemRemoved calls from being queued, you can use AddInventoryEventFilter with an empty FormList as an argument. To resume listening for item additions and removals, you can call [[RemoveAllInventoryEventFilters - ObjectReference|RemoveAllInventoryEventFilters]]. | *If you need to temporarily stop OnItemAdded and OnItemRemoved calls from being queued, you can use AddInventoryEventFilter with an empty FormList as an argument.

**This trick stops OnItemRemoved calls from ''being queued.'' It doesn't prevent the execution of function calls that have already been queued. To wit, using this trick from inside of OnItemRemoved won't stop Skyrim from dumping stacks when something calls RemoveAllItems(), because the first OnItemRemoved call only executes after the other hundred or so have been queued. You'd have to stop listening to inventory events before the item removals ever take place. | **This trick stops OnItemRemoved calls from ''being queued.''

*Remember that you can point multiple reference aliases at the player. Each can have their own inventory event filters and inventory event handlers, so you can filter OnItemAdded and OnItemRemoved differently. | |||
