The action of adding additional items to an **existing stack** of stackable items contained within a container type (crate/bag/etc) **does not** reset the persistence timer of the container as would be expected...
**This was found in game to impact bags but should impact any container type.**
**In my test I used bullets as my stackable type. I suspect all stackable types to behave the same.**
**I also found percentage based "mergeables" have the same issue (i.e. stacking/merging quantities of alcoholic tincture OR iodine**
**Note that I adjusted the persistence time of the bag I tested with as well as the item clean up distance to make testing easy. This will occur at the default values as well.**
