This parameter in my item bp, whether checked or unchecked ‘Consume item on use’, the item always ends up being consumed. How to fix this?
Could you tell me more about what settings you’re using?
It is possible that items that affect your stats/spawn actors get consumed regardless of that option being set.
Yeah, need a little more information on the item - is it a structure, a food item, etc.?
Are you using durability, which is how the water container canteen is used?
Many questions. 
things ive tried:
- changing durabilty
- changing parent class between item / weapon
- changing type between food / equipment / weapon
